Subject: [PATCH v1] scsi: target: remove unnecessary null checking for bio allocation
Date: Sun, 2 Feb 2025 18:02:08 +0900 [thread overview]
Message-ID: <20250202090208.26890-1-enjuk@amazon.com> (raw)
When __GFP_DIRECT_RECLAIM (included in GFP_NOIO) is specified,
bio_alloc_bioset() never fails to allocate a bio. For more details, see
the comment in bio_alloc_bioset() in block/bio.c
