       "double iput() on failure exit in lustre, racy removal of spliced
        dentries from ->s_anon in __d_materialise_dentry() plus a bunch of
        assorted RCU pathwalk fixes"
      
      The RCU pathwalk fixes end up fixing a couple of cases where we
      incorrectly dropped out of RCU walking, due to incorrect initialization
      and testing of the sequence locks in some corner cases.  Since dropping
      out of RCU walk mode forces the slow locked accesses, those corner cases
      slowed down quite dramatically.

      vfs: avoid non-forwarding large load after small store in path lookup · 9226b5b4
      Linus Torvalds authored
      The performance regression that Josef Bacik reported in the pathname
      lookup (see commit 99d263d4
      
       "vfs: fix bad hashing of dentries") made
      me look at performance stability of the dcache code, just to verify that
      the problem was actually fixed.  That turned up a few other problems in
      this area.
      
      There are a few cases where we exit RCU lookup mode and go to the slow
      serializing case when we shouldn't, Al has fixed those and they'll come
      in with the next VFS pull.
      
      But my performance verification also shows that link_path_walk() turns
      out to have a very unfortunate 32-bit store of the length and hash of
      the name we look up, followed by a 64-bit read of the combined hash_len
      field.  That screws up the processor store to load forwarding, causing
      an unnecessary hickup in this critical routine.
      
      It's caused by the ugly calling convention for the "hash_name()"
      function, and easily fixed by just making hash_name() fill in the whole
      'struct qstr' rather than passing it a pointer to just the hash value.
      
      With that, the profile for this function looks much smoother.

      vfs: fix bad hashing of dentries · 99d263d4
      Linus Torvalds authored
      Josef Bacik found a performance regression between 3.2 and 3.10 and
      narrowed it down to commit bfcfaa77
      
       ("vfs: use 'unsigned long'
      accesses for dcache name comparison and hashing"). He reports:
      
       "The test case is essentially
      
            for (i = 0; i < 1000000; i++)
                    mkdir("a$i");
      
        On xfs on a fio card this goes at about 20k dir/sec with 3.2, and 12k
        dir/sec with 3.10.  This is because we spend waaaaay more time in
        __d_lookup on 3.10 than in 3.2.
      
        The new hashing function for strings is suboptimal for <
        sizeof(unsigned long) string names (and hell even > sizeof(unsigned
        long) string names that I've tested).  I broke out the old hashing
        function and the new one into a userspace helper to get real numbers
        and this is what I'm getting:
      
            Old hash table had 1000000 entries, 0 dupes, 0 max dupes
            New hash table had 12628 entries, 987372 dupes, 900 max dupes
            We had 11400 buckets with a p50 of 30 dupes, p90 of 240 dupes, p99 of 567 dupes for the new hash
      
        My test does the hash, and then does the d_hash into a integer pointer
        array the same size as the dentry hash table on my system, and then
        just increments the value at the address we got to see how many
        entries we overlap with.
      
        As you can see the old hash function ended up with all 1 million
        entries in their own bucket, whereas the new one they are only
        distributed among ~12.5k buckets, which is why we're using so much
        more CPU in __d_lookup".
      
      The reason for this hash regression is two-fold:
      
       - On 64-bit architectures the down-mixing of the original 64-bit
         word-at-a-time hash into the final 32-bit hash value is very
         simplistic and suboptimal, and just adds the two 32-bit parts
         together.
      
         In particular, because there is no bit shuffling and the mixing
         boundary is also a byte boundary, similar character patterns in the
         low and high word easily end up just canceling each other out.
      
       - the old byte-at-a-time hash mixed each byte into the final hash as it
         hashed the path component name, resulting in the low bits of the hash
         generally being a good source of hash data.  That is not true for the
         word-at-a-time case, and the hash data is distributed among all the
         bits.
      
      The fix is the same in both cases: do a better job of mixing the bits up
      and using as much of the hash data as possible.  We already have the
      "hash_32|64()" functions to do that.

      Make hash_64() use a 64-bit multiply when appropriate · 23d0db76
      Linus Torvalds authored
      
      
      The hash_64() function historically does the multiply by the
      GOLDEN_RATIO_PRIME_64 number with explicit shifts and adds, because
      unlike the 32-bit case, gcc seems unable to turn the constant multiply
      into the more appropriate shift and adds when required.
      
      However, that means that we generate those shifts and adds even when the
      architecture has a fast multiplier, and could just do it better in
      hardware.
      
      Use the now-cleaned-up CONFIG_ARCH_HAS_FAST_MULTIPLIER (together with
      "is it a 64-bit architecture") to decide whether to use an integer
      multiply or the explicit sequence of shift/add instructions.

      Make ARCH_HAS_FAST_MULTIPLIER a real config variable · 72d93104
      Linus Torvalds authored
      
      
      It used to be an ad-hoc hack defined by the x86 version of
      <asm/bitops.h> that enabled a couple of library routines to know whether
      an integer multiply is faster than repeated shifts and additions.
      
      This just makes it use the real Kconfig system instead, and makes x86
      (which was the only architecture that did this) select the option.
      
      NOTE! Even for x86, this really is kind of wrong.  If we cared, we would
      probably not enable this for builds optimized for netburst (P4), where
      shifts-and-adds are generally faster than multiplies.  This patch does
      *not* change that kind of logic, though, it is purely a syntactic change
      with no code changes.
      
      This was triggered by the fact that we have other places that really
      want to know "do I want to expand multiples by constants by hand or
      not", particularly the hash generation code.

      alarmtimer: Do not signal SIGEV_NONE timers · 265b81d2
      Richard Larocque authored
      
      
      Avoids sending a signal to alarm timers created with sigev_notify set to
      SIGEV_NONE by checking for that special case in the timeout callback.
      
      The regular posix timers avoid sending signals to SIGEV_NONE timers by
      not scheduling any callbacks for them in the first place.  Although it
      would be possible to do something similar for alarm timers, it's simpler
      to handle this as a special case in the timeout.
      
      Prior to this patch, the alarm timer would ignore the sigev_notify value
      and try to deliver signals to the process anyway.  Even worse, the
      sanity check for the value of sigev_signo is skipped when SIGEV_NONE was
      specified, so the signal number could be bogus.  If sigev_signo was an
      unitialized value (as it often would be if SIGEV_NONE is used), then
      it's hard to predict which signal will be sent.

      This is a change in user-visible behavior, and may break existing

      jiffies: Fix timeval conversion to jiffies · d78c9300
      Andrew Hunter authored
      
      
      timeval_to_jiffies tried to round a timeval up to an integral number
      of jiffies, but the logic for doing so was incorrect: intervals
      corresponding to exactly N jiffies would become N+1. This manifested
      itself particularly repeatedly stopping/starting an itimer:
      
      setitimer(ITIMER_PROF, &val, NULL);
      setitimer(ITIMER_PROF, NULL, &val);
      
      would add a full tick to val, _even if it was exactly representable in
      terms of jiffies_ (say, the result of a previous rounding.)  Doing
      this repeatedly would cause unbounded growth in val.  So fix the math.
      
      Here's what was wrong with the conversion: we essentially computed
      (eliding seconds)
      
      jiffies = usec  * (NSEC_PER_USEC/TICK_NSEC)
      
      by using scaling arithmetic, which took the best approximation of
      NSEC_PER_USEC/TICK_NSEC with denominator of 2^USEC_JIFFIE_SC =
      x/(2^USEC_JIFFIE_SC), and computed:
      
      jiffies = (usec * x) >> USEC_JIFFIE_SC
      
      and rounded this calculation up in the intermediate form (since we
      can't necessarily exactly represent TICK_NSEC in usec.) But the
      scaling arithmetic is a (very slight) *over*approximation of the true
      value; that is, instead of dividing by (1 usec/ 1 jiffie), we
      effectively divided by (1 usec/1 jiffie)-epsilon (rounding
      down). This would normally be fine, but we want to round timeouts up,
      and we did so by adding 2^USEC_JIFFIE_SC - 1 before the shift; this
      would be fine if our division was exact, but dividing this by the
      slightly smaller factor was equivalent to adding just _over_ 1 to the
      final result (instead of just _under_ 1, as desired.)
      
      In particular, with HZ=1000, we consistently computed that 10000 usec
      was 11 jiffies; the same was true for any exact multiple of
      TICK_NSEC.
      
      We could possibly still round in the intermediate form, adding
      something less than 2^USEC_JIFFIE_SC - 1, but easier still is to
      convert usec->nsec, round in nanoseconds, and then convert using
      time*spec*_to_jiffies.  This adds one constant multiplication, and is
      not observably slower in microbenchmarks on recent x86 hardware.
      
      Tested: the following program:
      
      int main() {
        struct itimerval zero = {{0, 0}, {0, 0}};
        /* Initially set to 10 ms. */
        struct itimerval initial = zero;
        initial.it_interval.tv_usec = 10000;
        setitimer(ITIMER_PROF, &initial, NULL);
        /* Save and restore several times. */
        for (size_t i = 0; i < 10; ++i) {
          struct itimerval prev;
          setitimer(ITIMER_PROF, &zero, &prev);
          /* on old kernels, this goes up by TICK_USEC every iteration */
          printf("previous value: %ld %ld %ld %ld\n",
                 prev.it_interval.tv_sec, prev.it_interval.tv_usec,
                 prev.it_value.tv_sec, prev.it_value.tv_usec);

      futex: Unlock hb->lock in futex_wait_requeue_pi() error path · 13c42c2f
      Thomas Gleixner authored
      
      
      futex_wait_requeue_pi() calls futex_wait_setup(). If
      futex_wait_setup() succeeds it returns with hb->lock held and
      preemption disabled. Now the sanity check after this does:
      
              if (match_futex(&q.key, &key2)) {
      	   	ret = -EINVAL;
      		goto out_put_keys;
      	}
      
      which releases the keys but does not release hb->lock.
      
      So we happily return to user space with hb->lock held and therefor
      preemption disabled.
      
      Unlock hb->lock before taking the exit route.
