Subject: [PATCH v2 0/2] Fixes for batched TLB flushes
Date: Sat, 26 Mar 2016 01:25:03 -0700 [thread overview]
Message-ID: <1458980705-121507-1-git-send-email-namit@vmware.com> (raw)
The recent introduction of batched TLB flushes causes accounting problems in
vmstat and misses some tracepoints. In addition, I am afraid it might cause
problems in some platforms (Xen, UV) since it uses non-standard APIs.
v1->v2
* Added second patch to use standard api for invalidations
* cc'ing linux-mm
Nadav Amit (2):
x86/mm: TLB_REMOTE_SEND_IPI should count pages
mm/rmap: batched invalidations should use existing api
