      ALSA: pcm - Add logging of hwptr updates and interrupt updates · cedb8118
      Takashi Iwai authored
      Added the logging functionality to xrun_debug to record the hwptr
      updates via snd_pcm_update_hw_ptr() and snd_pcm_update_hwptr_interrupt(),
      corresponding to 16 and 8, respectively.
      For example,
      	# echo 9 > /proc/asound/card0/pcm0p/xrun_debug
      will record the position and other parameters at each period interrupt
      together with the normal XRUN debugging.

      ALSA: pcm - Fix regressions with VMware · 79452f0a
      Takashi Iwai authored
      VMware tends to report PCM positions and period updates at utterly
      wrong timing.  This screws up the recent PCM core code that tries
      to correct the position based on the irq timing.
      Now, when a backward irq position is detected, skip the update
      instead of rebasing.  (This is almost the old behavior before

      jbd2: fix race between write_metadata_buffer and get_write_access · 96577c43
      dingdinghua authored
      The function jbd2_journal_write_metadata_buffer() calls
      jbd_unlock_bh_state(bh_in) too early; this could potentially allow
      another thread to call get_write_access on the buffer head, modify the
      data, and dirty it, and allowing the wrong data to be written into the
      journal.  Fortunately, if we lose this race, the only time this will
      actually cause filesystem corruption is if there is a system crash or
      other unclean shutdown of the system before the next commit can take

      ext4: Fix ext4_mb_initialize_context() to initialize all fields · 833576b3
      Theodore Ts'o authored
      Pavel Roskin pointed out that kmemcheck indicated that
      ext4_mb_store_history() was accessing uninitialized values of
      ac->ac_tail and ac->ac_buddy leading to garbage in the mballoc
      history.  Fix this by initializing the entire structure to all zeros
      Also, two fields were getting doubly initialized by the caller of
      ext4_mb_initialize_context, so remove them for efficiency's sake.

      ext4: Fix buffer head reference leak in no-journal mode · e6b5d301
      Curt Wohlgemuth authored
      We found a problem with buffer head reference leaks when using an ext4
      partition without a journal.  In particular, calls to ext4_forget() would
      not to a brelse() on the input buffer head, which will cause pages they
      belong to to not be reclaimable.
      Further investigation showed that all places where ext4_journal_forget() and
      ext4_journal_revoke() are called are subject to the same problem.  The patch
      below changes __ext4_journal_forget/__ext4_journal_revoke to do an explicit
      release of the buffer head when the journal handle isn't valid.
