4.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jaegeuk Kim <[email protected]> commit e3ef18762f5757d3fb86f75ca59315db6d17d719 upstream. If end_io gets an error, we don't need to set the page as dirty, since we already set f2fs_stop_checkpoint which will not flush any data. This will resolve the following warning. ====================================================== [ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ] 4.4.0+ #9 Tainted: G O ------------------------------------------------------ xfs_io/26773 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire: (&(&sbi->inode_lock[i])->rlock){+.+...}, at: [<ffffffffc025483f>] update_dirty_page+0x6f/0xd0 [f2fs] and this task is already holding: (&(&q->__queue_lock)->rlock){-.-.-.}, at: [<ffffffff81396ea2>] blk_queue_bio+0x422/0x490 which would create a new lock dependency: (&(&q->__queue_lock)->rlock){-.-.-.} -> (&(&sbi->inode_lock[i])->rlock){+.+...} Signed-off-by: Jaegeuk Kim <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- fs/f2fs/data.c | 1 - 1 file changed, 1 deletion(-) --- a/fs/f2fs/data.c +++ b/fs/f2fs/data.c @@ -67,7 +67,6 @@ static void f2fs_write_end_io(struct bio f2fs_restore_and_release_control_page(&page); if (unlikely(bio->bi_error)) { - set_page_dirty(page); set_bit(AS_EIO, &page->mapping->flags); f2fs_stop_checkpoint(sbi); }
