From 46bac5352929f75c1ec0c2395b06dcbc0fbaee69 Mon Sep 17 00:00:00 2001 From: Xianting Tian Date: Tue, 20 Oct 2020 16:22:01 +0800 Subject: [PATCH] ext4: remove the null check of bio_vec page bv_page can't be NULL in a valid bio_vec, so we can remove the NULL check, as we did in other places when calling bio_for_each_segment_all() to go through all bio_vec of a bio.
