From cf32e41fa5f4fb88e4b4acf9cbf3acf9ac362553 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Thu, 30 Mar 2023 03:43:51 -0700 Subject: [PATCH] btrfs: use __bio_add_page to add single a page in rbio_add_io_sector The btrfs raid56 sector submission code uses bio_add_page() to add a page to a newly created bio. bio_add_page() can fail, but the return value is never checked. Use __bio_add_page() as adding a single page to a newly created bio is guaranteed to succeed. This brings us a step closer to marking bio_add_page() as __must_check.
