Re: [PATCH] btrfs: SSD related mount option dependency rework.
Any new comments? Cc: Satoru Sorry for the late reply. Unfortunately, it seems that your mail doesn't show in my inbox, but only occurs in patchwork. About writing the dependency in btrfs.txt, since the patch is based on the btrfs.txt, it already shows the dependency, so I'd like not to repeat them in btrfs.txt. Thanks, Qu Original Message Subject: [PATCH] btrfs: SSD related mount option dependency rework. From: Qu Wenruo quwen...@cn.fujitsu.com To: linux-btrfs@vger.kernel.org Date: 2014年08月01日 11:27 According to Documentations/filesystem/btrfs.txt, ssd/ssd_spread/nossd has their own dependency(See below), but only ssd_spread implying ssd is implemented. ssd_spread implies ssd, conflicts nossd. ssd conflicts nossd. nossd conflicts ssd and ssd_spread. This patch adds ssd{,_spread} confliction with nossd.
