rmap: wrap page_check_address() using __cond_lock()
The page_check_address() conditionally grabs *@ptlp in case of returning non-NULL. Rename and wrap it using __cond_lock() removes following warnings from sparse: mm/rmap.c:472:9: warning: context imbalance in 'page_mapped_in_vma' - unexpected unlock mm/rmap.c:524:9: warning: context imbalance in 'page_referenced_one' - unexpected unlock mm/rmap.c:706:9: warning: context imbalance in 'page_mkclean_one' - unexpected unlock mm/rmap.c:1066:9: warning: context imbalance in 'try_to_unmap_one' - unexpected unlock Signed-off-by: Namhyung Kim <namhyung@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
