Hi guys,
I have got a patch migrating from 3.11 version, and it works for
3.19.25/26.
It could be a regression. The patch looks like:
--- ufs/super.c 2015-09-26 17:18:46.000000000 +0800
+++ work/super.c 2015-10-12 23:46:40.964962685 +0800
@@ -805,6 +805,7 @@
UFSD("flag %u\n", (int)(sb->s_flags & MS_RDONLY));
mutex_init(&sbi->mutex);
+ mutex_init(&sbi->s_lock);
spin_lock_init(&sbi->work_lock);
INIT_DELAYED_WORK(&sbi->sync_work, delayed_sync_fs);
/*
Pls help review this patch.
Meanwhile, source tar downloaded by 3.19.0-26 quite matches what I get
from kernel, though they both look like 3.19.8.

At least the header is different, which is related to this patch.
