Subject: [PATCH AUTOSEL 4.14 21/67] block: allow max_discard_segments to be stacked
Date: Fri, 7 Sep 2018 00:37:34 +0000	[thread overview]
Message-ID: <20180907003716.57737-21-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180907003716.57737-1-alexander.levin@microsoft.com>

From: Mike Snitzer <snitzer@redhat.com>

[ Upstream commit 42c9cdfe1e11e083dceb0f0c4977b758cf7403b9 ]

Set max_discard_segments to USHRT_MAX in blk_set_stacking_limits() so
that blk_stack_limits() can stack up this limit for stacked devices.

before:

$ cat /sys/block/nvme0n1/queue/max_discard_segments
256
$ cat /sys/block/dm-0/queue/max_discard_segments
1

after:

$ cat /sys/block/nvme0n1/queue/max_discard_segments
256
$ cat /sys/block/dm-0/queue/max_discard_segments
256

Fixes: 1e739730c5b9e ("block: optionally merge discontiguous discard bios into a single request")
