From: John Garry <john.garry@xxxxxxxxxx>
[ Upstream commit 02f938e9fed1681791605ca8b96c2d9da9355f6a ]
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")
