Hi,
Here are two updates intended for those rare updater cases.
wrt numbers, I'm still trying to figure out this android boot environment (that calls cgroup_proc_write ipc paths) which might care about these changes. In the mean time, I'd like to know if anyone has any objections to these optimizations.
Passed kernel builds with lockdep, as well as an overnight run doing locktoture.
Thanks.
