Subject: ntfs: use find_get_page_flags() to mark page accessed as it is no longer marked later on
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5272d036b280d43a06ab790030609225480d2009;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ntfs: use find_get_page_flags() to mark page accessed as it is no longer marked later on

Mel Gorman's commit 2457aec63745 ("mm: non-atomically mark page accessed
during page cache allocation where possible") removed mark_page_accessed()
calls from NTFS without updating the matching find_lock_page() to
find_get_page_flags(GFP_LOCK | FGP_ACCESSED) thus causing the page to
never be marked accessed.

This patch fixes that.
