Linus Torvalds 3b3bea6d4b cgroup: Fixes for v7.1-rc1 
- Fix UAF race in psi pressure_write() against cgroup file release by
   extending cgroup_mutex coverage and ordering of->priv access after
   cgroup_kn_lock_live().
 
 - Fix integer overflow in rdmacg_try_charge() when usage equals INT_MAX
   by performing the increment in s64.
 
 - Fix asymmetric DL bandwidth accounting on cpuset attach rollback by
   recording the CPU used by dl_bw_alloc() so cancel_attach() returns
   the reservation to the same root domain.
 
 - Fix nr_dying_subsys_* race that briefly showed 0 in cgroup.stat after
   rmdir by incrementing from kill_css() instead of offline_css().
 
 - Typo fix in cgroup-v2 documentation.
