[PATCH] 2.4.7-ac4/ac5 dies due to double unlock

[Petr Vandrovec]

Hi Alan,
  double-unlock on sb_lock in try_to_sync_unused inodes when 
try_to_sync_unused_list() returns 0... It is reliably
triggered by xmms loading mp3 tags from vfat...

  Originally from 2.4.7-ac4, but still unfixed in -ac5.
					Thanks,
