Dmitry Monakhov 88c6b61ff1 ext4: move_extent improve bh vanishing success factor ... Xiaoguang Wang has reported sporadic EBUSY failures of ext4/302 Unfortunetly there is nothing we can do if some other task holds BH's refenrence. So we must return EBUSY in this case. But we can try kicking the journal to see if the other task releases the bh reference after the commit is complete. Also decrease false positives by properly checking for ENOSPC and retrying the allocation after kicking the journal --- which is done by ext4_should_retry_alloc(). [ Modified by tytso to properly check for ENOSPC. ] Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Theodore Ts'o <tytso@mit.edu>		2014-11-05 11:52:38 -05:00
