Subject: [PATCH] blk-mq-debugfs: Add decode for BLK_MQ_F_TAG_HCTX_SHARED
Date: Fri, 8 Jan 2021 16:55:37 +0800	[thread overview]
Message-ID: <1610096137-187414-1-git-send-email-john.garry@huawei.com> (raw)

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")
