      [PATCH] disk stats accounting fix · b8ac7066
      Jens Axboe authored
      We should only account file system requests, ones originating from
      __make_request(). Otherwise it skews the counters and they go negative
      really fast.

      [PATCH] devfs deadlock fix · 1cf2ec10
      Andrew Morton authored
      From: Andrey Borzenkov <arvidjaar@mail.ru>
      
      I finally hit a painfully trivial way to reproduce another long standing devfs
      problem - deadlock between devfs_lookup and devfs_d_revalidate_wait. When
      devfs_lookup releases directory i_sem devfs_d_revalidate_wait grabs it (it
      happens not for every path) and goes to wait to be waked up. Unfortunately,
      devfs_lookup attempts to acquire directory i_sem before ever waking it up ...
      
      To reproduce (2.5.74 UP or SMP - does not matter, single CPU system)
      
      ls /dev/foo & rm -f /dev/foo &
      
      or possibly in a loop but then it easily fills up process table. In my case it
      hangs 100% reliably - on 2.5 OR 2.4.
      
      The current fix is to move re-acquire of i_sem after all
      devfs_d_revalidate_wait waiters have been waked up.  Much better fix would be
      to ensure that ->d_revalidate either is always called under i_sem or always
      without.  But that means the very heart of VFS and I do not dare to touch it.
      
      The fix has been tested on 2.4 (and is part of unofficial Mandrake Club
      kernel); I expected the same bug is in 2.5; I just was stupid not seeing the
      way to reproduce it before.
