Subject: [PATCH] block: Remove unused flush_queue_delayed in struct
blk_flush_queue
References: bsc#1175995,jsc#SLE-15608
Git-commit: 172ce41db4b2d6fa5956c4baa63475b15f5d4bd8
Patch-mainline: v5.8-rc1
The flush_queue_delayed was introdued to hold queue if flush is
running for non-queueable flush drive by commit 3ac0cc450870
("hold queue if flush is running for non-queueable flush drive"),
but the non mq parts of the flush code had been removed by
commit 7e992f847a08 ("block: remove non mq parts from the flush code"),
as well as removing the usage of the flush_queue_delayed flag.
Thus remove the unused flush_queue_delayed flag.
