[lkp] [zsmalloc] 44f43e99fe: will-it-scale.scalability +15.0% improvement
From: kernel test robot
Date: Thu May 12 2016 - 21:41:40 EST
FYI, we noticed will-it-scale.scalability +15.0% improvement due to commit:
commit 44f43e99fe70833058482d183e99fdfd11220996 ("zsmalloc: fix zs_can_compact() integer overflow")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase - will-it-scale
on test machine - xps: 8 threads Nehalem with 4G memory
