This is a note to let you know that I've just added the patch titled block: use proper return value from bio_failfast() to the 6.2-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: block-use-proper-return-value-from-bio_failfast.patch and it can be found in the queue-6.2 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5384c09f4a604a1bd50145c68d13460ecb15d4e1 Author: Jens Axboe <axboe@xxxxxxxxx> Date: Thu Feb 16 19:39:15 2023 -0700 block: use proper return value from bio_failfast() [ Upstream commit f3ca73862453ac1e64fc6968a14bf66d839cd2d8 ] kernel test robot complains about a type mismatch: block/blk-merge.c:984:42: sparse: expected restricted blk_opf_t const [usertype] ff block/blk-merge.c:984:42: sparse: got unsigned int block/blk-merge.c:1010:42: sparse: sparse: incorrect type in initializer (different base types) @@ expected restricted blk_opf_t const [usertype] ff @@ got unsigned int @@ block/blk-merge.c:1010:42: sparse: expected restricted blk_opf_t const [usertype] ff block/blk-merge.c:1010:42: sparse: got unsigned int because bio_failfast() is return an unsigned int rather than the appropriate blk_opt_f type.
