      Linus Torvalds authored
      This reverts commit 10dbe196
      The resource struct is still 32-bit, so trying to save a 64-bit memory
      size there obviously won't work.
      When we merge the 64-bit resource series, we can re-enable this.

      Alternative fix for MMC oops on unmount after removal · 032ebf26
      Linus Torvalds authored
      Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on
      disk removal), so that other users that may still have a ref to the disk
      won't try to use the stale pointer.
      Also move the KOBJ_REMOVE uevent handler up, so that the uevent still
      has access to the driverfs_dev data.
      This all should hopefully fix the problems with MMC umounts after device
      removals that caused commit 56cf6504 and
      its reversal (1a2acc9e
      Original problem reported by Todd Blumer and others.

      IB: refcount race fixes · 1b52fa98
      Sean Hefty authored
      Fix race condition during destruction calls to avoid possibility of
      accessing object after it has been freed.  Instead of waking up a wait
      queue directly, which is susceptible to a race where the object is
      freed between the reference count going to 0 and the wake_up(), use a
      completion to wait in the function doing the freeing.

      IB/ipath: Properly terminate PCI ID table · 6f4bb3d8
      Roland Dreier authored
      The ipath driver's table of PCI IDs needs a { 0, } entry at the end.
      This makes all of the device aliases visible to userspace so hotplug
      loads the module for all supported devices.  Without the patch,
      modinfo ipath_core only shows:
          alias:          pci:v00001FC1d0000000Dsv*sd*bc*sc*i*
      instead of the correct:
          alias:          pci:v00001FC1d00000010sv*sd*bc*sc*i*

      [NEIGH]: Fix IP-over-ATM and ARP interaction. · bd89efc5
      Simon Kelley authored
      The classical IP over ATM code maintains its own IPv4 <-> <ATM stuff>
      ARP table, using the standard neighbour-table code. The
      neigh_table_init function adds this neighbour table to a linked list
      of all neighbor tables which is used by the functions neigh_delete()
      neigh_add() and neightbl_set(), all called by the netlink code.
      Once the ATM neighbour table is added to the list, there are two
      tables with family == AF_INET there, and ARP entries sent via netlink
      go into the first table with matching family. This is indeterminate
      and often wrong.
      To see the bug, on a kernel with CLIP enabled, create a standard IPv4
      ARP entry by pinging an unused address on a local subnet. Then attempt
      to complete that entry by doing
      ip neigh replace <ip address> lladdr <some mac address> nud reachable
      Looking at the ARP tables by using 
      ip neigh show
      will reveal two ARP entries for the same address. One of these can be
      found in /proc/net/arp, and the other in /proc/net/atm/arp.
      This patch adds a new function, neigh_table_init_no_netlink() which
      does everything the neigh_table_init() does, except add the table to
      the netlink all-arp-tables chain. In addition neigh_table_init() has a
      check that all tables on the chain have a distinct address family.
      The init call in clip.c is changed to call
      Since ATM ARP tables are rather more complicated than can currently be
      handled by the available rtattrs in the netlink protocol, no
      functionality is lost by this patch, and non-ATM ARP manipulation via
      netlink is rescued. A more complete solution would involve a rtattr
      for ATM ARP entries and some way for the netlink code to give
      neigh_add and friends more information than just address family with
      which to find the correct ARP table.
      [ I've changed the assertion checking in neigh_table_init() to not
        use BUG_ON() while holding neigh_tbl_lock.  Instead we remember that
        we found an existing tbl with the same family, and after dropping
        the lock we'll give a diagnostic kernel log message and a stack dump.

      Linus Torvalds authored
      This reverts commit 56cf6504
      Both Erik Mouw and Andrew Vasquez independently pinpointed this commit
      as causing problems, where the slab cache for a driver is never released
      (most obviously causing problems when immediately re-loading that
      driver, resulting in a "kmem_cache_create: duplicate cache <xyz>"
      message, but it can also cause other trouble).
      James Bottomley dug into it, and reports:
        "OK, here's the scoop.  The problem patch adds a get of driverfs_dev in
         add_disk(), but doesn't put it again until disk_release() (which occurs
         on final put_disk() of the gendisk).
         However, in SCSI, the driverfs_dev is the sdev_gendev.  That means
         there's a reference held on sdev_gendev  until final disk put.
         Unfortunately, we use the driver model driver_remove to trigger
         del_gendisk (which removes the gendisk from visibility and decrements
         the refcount), so we've introduced an unbreakable deadlock in the
         reference counting with this.
         I suggest simply reversing this patch at the moment.  If Russell and
         Jens can tell me what they're trying to do I'll see if there's another
         way to do it."
      so hereby the patch gets reverted, waiting for a better fix.

      [PATCH] USB: Emagic USB firmware loading fixes · 16c23f7d
      Monty authored
      It's become apparent as machines get faster that the emagic kernel firmware
      loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
      never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
      time.  The bug is seen as a hung USB box and the kernel error:
      drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
      error = -110
      The patch below inserts a delay after deasserting reset to allow the box to
      settle before a new command is issued.  This affects only device startup.

      [BLOCK] limit request_fn recursion · dac07ec1
      Jens Axboe authored
      Don't recurse back into the driver even if the unplug threshold is met,
      when the driver asks for a requeue. This is both silly from a logical
      point of view (requeues typically happen due to driver/hardware
      shortage), and also dangerous since we could hit an endless request_fn
      -> requeue -> unplug -> request_fn loop and crash on stack overrun.
      Also limit blk_run_queue() to one level of recursion, similar to how
      blk_start_queue() works.
      This patch fixed a real problem with SLES10 and lpfc, and it could hit
      any SCSI lld that returns non-zero from it's ->queuecommand() handler.
