Matthew Wilcox (Oracle) 2295664518 block: Fix page_is_mergeable() for compound pages ... [ Upstream commit d81665198b ] If we pass in an offset which is larger than PAGE_SIZE, then page_is_mergeable() thinks it's not mergeable with the previous bio_vec, leading to a large number of bio_vecs being used. Use a slightly more obvious test that the two pages are compatible with each other. Fixes: 52d52d1c98 ("block: only allow contiguous page structs in a bio_vec") Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Reviewed-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-09-03 11:26:54 +02:00
