      ext4: fix unjournaled inode bitmap modification · ffb5387e
      Eric Sandeen authored
      commit 119c0d44
      
       changed
      ext4_new_inode() such that the inode bitmap was being modified
      outside a transaction, which could lead to corruption, and was
      discovered when journal_checksum found a bad checksum in the
      journal during log replay.
      
      Nix ran into this when using the journal_async_commit mount
      option, which enables journal checksumming.  The ensuing
      journal replay failures due to the bad checksums led to
      filesystem corruption reported as the now infamous
      "Apparent serious progressive ext4 data corruption bug"
      
      [ Changed by tytso to only call ext4_journal_get_write_access() only
        when we're fairly certain that we're going to allocate the inode. ]
      
      I've tested this by mounting with journal_checksum and
      running fsstress then dropping power; I've also tested by
      hacking DM to create snapshots w/o first quiescing, which
      allows me to test journal replay repeatedly w/o actually
      power-cycling the box.  Without the patch I hit a journal
      checksum error every time.  With this fix it survives
      many iterations.

        I found that the modules for the network was not being installed.
        This was due to the config CONFIG_MODULES_USE_ELF_RELA that came
        before CONFIG_MODULES, and confused ktest in thinking that
        CONFIG_MODULES=y was not found.

      Lock splice_read and splice_write functions · 1a25b1c4
      Mikulas Patocka authored
      Functions generic_file_splice_read and generic_file_splice_write access
      the pagecache directly. For block devices these functions must be locked
      so that block size is not changed while they are in progress.
      
      This patch is an additional fix for commit b87570f5
      
       ("Fix a crash
      when block device is read and block size is changed at the same time")
      that locked aio_read, aio_write and mmap against block size change.

      percpu-rw-semaphores: use rcu_read_lock_sched · 1bf11c53
      Mikulas Patocka authored
      
      
      Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched
      instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu.
      
      This is an optimization. The RCU-protected region is very small, so
      there will be no latency problems if we disable preempt in this region.
      
      So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates
      to preempt_disable / preempt_disable. It is smaller (and supposedly
      faster) than preemptible rcu_read_lock / rcu_read_unlock.

      percpu-rw-semaphores: use light/heavy barriers · 5c1eabe6
      Mikulas Patocka authored
      
      
      This patch introduces new barrier pair light_mb() and heavy_mb() for
      percpu rw semaphores.
      
      This patch fixes a bug in percpu-rw-semaphores where a barrier was
      missing in percpu_up_write.
      
      This patch improves performance on the read path of
      percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in
      percpu_up_read. This patch changes it to a compiler barrier and removes
      the "#if defined(X86) ..." condition.
