Dmitry Monakhov 82e5422911 ext4: fix unwritten counter leakage ... ext4_set_io_unwritten_flag() will increment i_unwritten counter, so once we mark end_io with EXT4_END_IO_UNWRITTEN we have to revert it back on error path. - add missed error checks to prevent counter leakage - ext4_end_io_nolock() will clear EXT4_END_IO_UNWRITTEN flag to signal that conversion finished. - add BUG_ON to ext4_free_end_io() to prevent similar leakage in future. Visible effect of this bug is that unaligned aio_stress may deadlock Reviewed-by: Jan Kara <jack@suse.cz> Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>		2012-09-28 23:36:25 -04:00
