This is the 4th group of driver conversion examples. This set is complete, as there are only a few drivers which use __register_blkdev(). The __register_blkdev() call uses an optional probe call, and if set will be used when blk_request_module() is called for the block device. Since these probe calls can fail, now that we added *add_disk*() error handling, take advatage of this and extend the probe call to capture the errors. There are only a few drivers which benefit from this. The meat of the work is the last patch, which includes all driver conversions. The rest of the patches are adding add_disk() error handling in the other places of the drivers. Luis Chamberlain (12): floppy: fix add_disk() assumption on exit floppy: use blk_cleanup_disk() floppy: add error handling support for add_disk() scsi/sd: use blk_cleanup_queue() insted of put_disk() scsi/sd: add error handling support for add_disk() scsi/sr: use blk_cleanup_disk() instead of put_disk() scsi/sr: add error handling support for add_disk() block/ataflop: use the blk_cleanup_disk() helper block/ataflop: add a helper for removing disks block/ataflop add error handling support for add_disk() block/brd: add error handling support for add_disk() block: make probe in blk_request_module() return an error block/genhd.c | 15 ++++++---- drivers/block/ataflop.c | 66 ++++++++++++++++++++++++----------------- drivers/block/brd.c | 17 ++++++++--- drivers/block/floppy.c | 48 ++++++++++++++---------------- drivers/block/loop.c | 6 ++-- drivers/scsi/sd.c | 11 +++++-- drivers/scsi/sr.c | 7 +++-- fs/block_dev.c | 5 +++- include/linux/genhd.h | 4 +-- 9 files changed, 105 insertions(+), 74 deletions(-) -- 2.27.0
