Hi,
These patches fix a memory leak in per-cpu areas in v4.9.y
The following command sequence
while :; do c=$(docker create busybox) docker start $c docker stop $c docker rm $c done
causes the number of pcpu_get_vm_area entries in /proc/vmallocinfo to grow.
The commit d6cffbbe9a7e ("proc/sysctl: prune stale dentries during unregistering") fixes the issue and the commits ace0c791e6c3 ("proc/sysctl: Don't grab i_lock under sysctl_lock.") and 2fd1d2c4ceb2 ("proc: Fix proc_sys_prune_dcache to hold a sb reference") are the follow-up fixups.
I've also checked v4.4 and the issue does not appear there.

What is the git commit ids of these patches that are in Linus's tree? I need those to be able to apply this.

Thanks, now queued up. Any reason why you did not sign off on the backports?
