From 0fa5b08cf6e17b0a64ffcc5894d8efe186691ab8 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 31 May 2023 04:50:33 -0700 Subject: zonefs: use __bio_add_page for adding single page to bio The zonefs superblock reading 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.
