Hello, Linus.
cgroup changes for v4.11. Several noteworthy changes.
* Parav's rdma controller is finally merged. It is very straight
forward and can limit the abosolute numbers of common rdma
constructs used by different cgroups.
* kernel/cgroup.c got too chubby and disorganized. Created
kernel/cgroup/ subdirectory and moved all cgroup related files under
kernel/ there and reorganized the core code. This hurts for
backporting patches but was long overdue.
* cgroup v2 process listing reimplemented so that it no longer depends
on allocating a buffer large enough to cache the entire result to
sort and uniq the output. v2 has always mangled the sort order to
ensure that users don't depend on the sorted output, so this
shouldn't surprise anybody. This makes the pid listing functions
use the same iterators that are used internally, which have to have
the same iterating capabilities anyway.
* perf cgroup filtering now works automatically on cgroup v2. This
patch was posted a long time ago but somehow fell through the
cracks.
* Misc fixes asnd documentation updates.
Thanks.
