blk-mq-debugfs: Add decode for BLK_MQ_F_TAG_HCTX_SHARED
Showing the hctx flags for when BLK_MQ_F_TAG_HCTX_SHARED is set gives something like: root@debian:/home/john# more /sys/kernel/debug/block/sda/hctx0/flags alloc_policy=FIFO SHOULD_MERGE|TAG_QUEUE_SHARED|3 Add the decoding for that flag. Fixes: 32bc15afed04b ("blk-mq: Facilitate a shared sbitmap per tagset") Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
