Subject: [PATCH 6.12.y] block: make bio_integrity_map_user() static inline
Date: Fri, 29 May 2026 10:53:34 +0200 [thread overview]
Message-ID: <20260529085334.937482-1-linuxoid@gmail.com> (raw)
From: Jens Axboe <axboe@kernel.dk>
If CONFIG_BLK_DEV_INTEGRITY isn't set, then the dummy helper must be
static inline to avoid complaints about the function being unused.
Fixes: fe8f4ca7107e ("block: modify bio_integrity_map_user to accept iov_iter as argument")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202411300229.y7h60mDg-lkp@intel.com/
Signed-off-by: Jens Axboe <axboe@kernel.dk>
(cherry picked from commit 546d191427cf5cf3215529744c2ea8558f0279db)
The same build break is now reported on stable-rc/linux-6.12.y by KernelCI.
Verified the upstream cherry-pick applies cleanly on top of 97928cc88900a
(Linux 6.12.92-rc1) and that block/bdev.o + block/fops.o compile cleanly
afterwards with i386_defconfig (which leaves CONFIG_BLK_DEV_INTEGRITY
unset). Without the fix both files trip:
include/linux/bio-integrity.h:101:12: error: 'bio_integrity_map_user' defined but not used [-Werror=unused-function]
