This initialization is spread all over the block drivers. This avoids repetation of inialization code of the tag set in current block drivers and any future ones. P.S. I'm aware of the EXPORT_SYMBOL_GPL() checkpatch warn just to make get some feedback to so I can remove the RFC tag. -ck Chaitanya Kulkarni (21): block: add and use init tagset helper loop: use lib tagset init helper nbd: use lib tagset init helper rnbd: use lib tagset init helper bsg-lib: use lib tagset init helper rnbd-clt: use lib tagset init helper virtio-blk: use lib tagset init helper scsi: use lib tagset init helper block: use lib tagset init helper amiflop: use lib tagset init helper floppy: use lib tagset init helper mtip32xx: use lib tagset init helper z3ram: use lib tagset init helper scm_blk: use lib tagset init helper ubi: use lib tagset init helper mmc: core: use lib tagset init helper dasd: use lib tagset init helper nvme-core: use lib tagset init helper for I/O q nvme-core: use lib tagset init helper for adminq nvme-apple: use lib tagset init helper nvme-pci: use lib tagset init helper block/blk-mq.c | 27 ++++++++++++++++++++++----- block/bsg-lib.c | 9 +++------ drivers/block/amiflop.c | 8 +++----- drivers/block/floppy.c | 7 ++----- drivers/block/loop.c | 12 ++++-------- drivers/block/mtip32xx/mtip32xx.c | 13 ++++--------- drivers/block/nbd.c | 11 +++-------- drivers/block/null_blk/main.c | 10 +++------- drivers/block/rbd.c | 11 +++++------ drivers/block/rnbd/rnbd-clt.c | 25 +++++++++++-------------- drivers/block/virtio_blk.c | 14 +++++--------- drivers/block/z2ram.c | 7 ++----- drivers/mmc/core/queue.c | 9 +++------ drivers/mtd/ubi/block.c | 11 +++-------- drivers/nvme/host/apple.c | 25 ++++++++----------------- drivers/nvme/host/core.c | 21 +++++---------------- drivers/nvme/host/pci.c | 25 +++++++------------------ drivers/s390/block/dasd_genhd.c | 9 +++------ drivers/s390/block/scm_blk.c | 10 +++------- drivers/scsi/scsi_lib.c | 13 +++++-------- include/linux/blk-mq.h | 5 +++++ 21 files changed, 109 insertions(+), 173 deletions(-)
