Subject: [PATCH 1/5] blk-mq: Rename BLK_EH_DONE into BLK_EH_DONT_RESET_TIMER
Date: Fri, 27 Jul 2018 09:20:38 -0700	[thread overview]
Message-ID: <20180727162042.13425-2-bart.vanassche@wdc.com> (raw)
In-Reply-To: <20180727162042.13425-1-bart.vanassche@wdc.com>

If a block driver timeout handler returns BLK_EH_DONE that means
either that the request has been completed or that the block driver
still owns the request. Since the name BLK_EH_DONE is misleading,
change it into BLK_EH_DONT_RESET_TIMER.

Fixes: 88b0cfad2888 ("block: document the blk_eh_timer_return values")
Fixes: 6600593cbd93 ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE")
