Subject: [PATCH] block: Fix uninitialized symbol 'bio' in blk_rq_prep_clone
Date: Fri, 4 Oct 2024 15:38:42 +0530 [thread overview]
Message-ID: <20241004100842.9052-1-surajsonawane0215@gmail.com> (raw)
Fix the uninitialized symbol 'bio' in the function blk_rq_prep_clone
to resolve the following error:
block/blk-mq.c:3199 blk_rq_prep_clone() error: uninitialized symbol 'bio'.
Initialize 'bio' to NULL to prevent undefined behavior from uninitialized
access and safe cleanup in case of failure.
