Petr Cermak 695f055936 fs/proc/task_mmu.c: add user-space support for resetting mm->hiwater_rss (peak RSS) 
Peak resident size of a process can be reset back to the process's
current rss value by writing "5" to /proc/pid/clear_refs.  The driving
use-case for this would be getting the peak RSS value, which can be
retrieved from the VmHWM field in /proc/pid/status, per benchmark
iteration or test scenario.
