Subject: mm: don't mark_page_accessed in shmem_fault
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=390722baa7fc447b0a4f0c3c3f537ed056dbc944;p=openwrt%2Fstaging%2Fblogic.git

mm: don't mark_page_accessed in shmem_fault

Following "mm: don't mark_page_accessed in fault path", which now
places a mark_page_accessed() in zap_pte_range(), we should remove
the mark_page_accessed() from shmem_fault().
