Subject: [PATCH STABLE ONLY] add missing page refcount overflow checks
Date: Fri, 29 Nov 2019 10:03:48 +0100 [thread overview]
Message-ID: <20191129090351.3507-1-vbabka@suse.cz> (raw)
This collection of patches add the missing overflow checks in arch-specific
gup.c variants for x86 and s390. Those were missed in backport of 8fde12ca79af
("mm: prevent get_user_pages() from overflowing page refcount") as mainline
had a single gup.c implementation at that point. See individual patches for
details.
