These percpu counters are referenced in free_ipcs->freeque, so destroy them later. Fixes: 72d1e611082e ("ipc/msg: mitigate the lock contention with percpu counter") Reported-by: syzbot+96e659d35b9d6b541152@syzkaller.appspotmail.com Tested-by: Mark Rutland <mark.rutland@arm.com> Cc: Jiebin Sun <jiebin.sun@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
