Descriptions
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: fix list corruption from resetting io stat
Since commit 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()"),
each iostat instance is added to blkcg percpu list, so blkcg_reset_stats()
can't reset the stat instance by memset(), otherwise the llist may be
corrupted.
Fix the issue by only resetting the counter part.
