Commit 6f890df0 ("f2fs: fix out-of-order execution in f2fs_issue_flush")
uses waitqueue_active to wake up issue_flush thread, but there is no
wait entry to wake in this queue, so change it back to use the original
fcc->dispatch_list to wake up issue_flush thread.Signed-off-by: Yunlong Song <[email protected]> --- fs/f2fs/segment.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/f2fs/segment.c b/fs/f2fs/segment.c index 503a98a..5aa5ee4e 100644 --- a/fs/f2fs/segment.c +++ b/fs/f2fs/segment.c @@ -612,7 +612,7 @@ int f2fs_issue_flush(struct f2fs_sb_info *sbi, nid_t ino) /* update issue_list before we wake up issue_flush thread */ smp_mb(); - if (waitqueue_active(&fcc->flush_wait_queue)) + if (!fcc->dispatch_list) wake_up(&fcc->flush_wait_queue); if (fcc->f2fs_issue_flush) { -- 1.8.5.2
