Subject: [PATCH v4 5/6] generic/413, xfs/260: Improve format operation for PMD fault testing
Date: Wed, 1 Jul 2020 12:36:59 +0800
Message-ID: <20200701043700.6473-6-yangx.jy@cn.fujitsu.com> (raw)
In-Reply-To: <20200701043700.6473-1-yangx.jy@cn.fujitsu.com>

1) Simple code and fix the wrong value of stripe_width by _scratch_mkfs_geom().
2) Get hugepage size by _get_hugepagesize() and replace fixed 2M with
   hugepage size because hugepage size/PMD_SIZE is not 2M on some
   arches(e.g. hugepage size/PMD_SIZE is 512M on arm64).
3) For debugging, redirect the output of mkfs to $seqres.full.
