Description
Description
In the Linux kernel, the following vulnerability has been resolved:
xfs: drop dquot flush lock when we can't find a buffer to flush
LOLLM noticed that xfs_qm_flush_one fails to drop the dquot flush lock
if it can't grab the buffer associated with the dquot. Since there's no
buffer, nobody else is going to drop the dqflock, so we need to do it
ourselves.
