Subject: [PATCH 15/15] btrfs-progs: consolidate num_stripes setting for striping RAID levels
Date: Wed, 10 Jun 2020 21:32:58 +0900 [thread overview]
Message-ID: <20200610123258.12382-16-johannes.thumshirn@wdc.com> (raw)
In-Reply-To: <20200610123258.12382-1-johannes.thumshirn@wdc.com>
All striping RAID Levels use the same method to set the number of RAID
stripes, so consolidate it.
