Subject: [PATCH 07/13] btrfs-progs: lowmem: delete unaligned bytes extent data under repair
Date: Tue, 23 Oct 2018 17:41:41 +0800	[thread overview]
Message-ID: <20181023094147.7906-8-suy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20181023094147.7906-1-suy.fnst@cn.fujitsu.com>

If found a extent data item has unaligned part, lowmem repair
just deletes it.
