Subject: [PATCH 1/4] btrfs: print-tree: print stripe len of a chunk
Date: Thu, 23 Jul 2015 17:18:07 +0800	[thread overview]
Message-ID: <1437643090-13920-2-git-send-email-quwenruo@cn.fujitsu.com> (raw)
In-Reply-To: <1437643090-13920-1-git-send-email-quwenruo@cn.fujitsu.com>

Although it is fixed to BTRFS_STRIPE_LEN(64K) now, it's still used in a
lot of codes, just output it for user who want to trace the source of
stripe_len in btrfs_map_bio() codes.
