--- Comment #19 from Byreddy <bsrirama at redhat.com> ---
Verified this bug using the build "glusterfs-3.7.9-4"

After doing mount and umount of volume for 300 times, the memory footprint with
and without fix is below.

Without Fix:
-----------
PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND       
5257 root      20   0 41.496g 153400   4480 S   0.0  8.1   0:30.08 glusterd.

With Fix:
---------
PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND       
4245 root      20   0 1459040  74808   4752 S   0.0  4.0   0:40.21 glusterd   

With the fix, memory over commit is not happening, moving to verified state.
