The following patch addresses the issue reported by Fengguang Wu
regarding this tip commit 1018016c706f.

---------------------------------------------------------------------------
The description for struct thread_group_cputimer contains the 'cputime'
and 'lock' members, which are not valid anymore since

tip commit 1018016c706f ("sched, timer: Replace spinlocks with atomics
in thread_group_cputimer(), to improve scalability")

modified/removed those fields. This patch updates the description
to reflect those changes.
