Subject: [PATCH 03/13] NFS: Cleanup - move nfs_write_inode() into fs/nfs/write.c
Date: Wed, 10 Feb 2010 12:03:23 -0500 [thread overview]
Message-ID: <1265821413-21618-4-git-send-email-Trond.Myklebust@netapp.com> (raw)
In-Reply-To: <1265821413-21618-3-git-send-email-Trond.Myklebust@netapp.com>
The sole purpose of nfs_write_inode is to commit unstable writes, so
move it into fs/nfs/write.c, and make nfs_commit_inode static.
