Subject: NUMA memchr_inv() in mm/vmstat.c:need_update()?
Date: Fri, 2 Nov 2018 14:44:11 +0200 [thread overview]
Message-ID: <1541162651.27706.93.camel@nokia.com> (raw)
Hi,
The commit 1d90ca897A changed the type of the vm_numa_stat_diff
from s8 into u16. It also changed the associated BUILD_BUG_ON()
in need_update(), but didn't touch the memchr_inv() call after
it. Is the memchr_inv() call still supposed to cover the whole
array or am I just misreading the code?
