Subject: [PATCH 5.1 038/122] md: batch flush requests.
Date: Thu, 23 May 2019 21:06:00 +0200 [thread overview]
Message-ID: <20190523181709.823320592@linuxfoundation.org> (raw)
In-Reply-To: <20190523181705.091418060@linuxfoundation.org>
From: NeilBrown <neilb@suse.com>
commit 2bc13b83e6298486371761de503faeffd15b7534 upstream.
Currently if many flush requests are submitted to an md device is quick
succession, they are serialized and can take a long to process them all.
We don't really need to call flush all those times - a single flush call
can satisfy all requests submitted before it started.
So keep track of when the current flush started and when it finished,
allow any pending flush that was requested before the flush started
to complete without waiting any more.
Test results from Xiao:
Test is done on a raid10 device which is created by 4 SSDs. The tool is
dbench.
