Subject: [PATCH 15/24] orangefs: let setattr write to cached inode
Date: Tue, 20 Mar 2018 17:02:25 +0000	[thread overview]
Message-ID: <20180320170234.1412-16-martin@omnibond.com> (raw)
In-Reply-To: <20180320170234.1412-1-martin@omnibond.com>

This is a fairly big change, but ultimately it's not a lot of code.

Implement write_inode and then avoid the call to orangefs_inode_setattr
within orangefs_setattr.
