[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.5.7.30 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wang Shilong <wangsl.fnst@xxxxxxxxxxxxxx>

commit 90515e7f5d7d24cbb2a4038a3f1b5cfa2921aa17 upstream.

We may return early in btrfs_drop_snapshot(), we shouldn't
call btrfs_std_err() for this case, fix it.
