Subject: [PATCH 2/2] Btrfs: don't change inode flag of the dest clone file
Date: Wed, 14 Sep 2011 13:25:36 +0800	[thread overview]
Message-ID: <4E703AD0.2060202@cn.fujitsu.com> (raw)
In-Reply-To: <4E703AC1.5060205@cn.fujitsu.com>

The dst file will have the same inode flags with dst file after
file clone, and I think it's unexpected.

For example, the dst file will suddenly become immutable after
getting some share of data with src file, if the src is immutable.
