Subject: [PATCH 2/2] xfs_export_operations.commit_metadata
Date: Wed, 17 Feb 2010 14:05:16 -0600	[thread overview]
Message-ID: <20100217200516.13409.97524.stgit@case> (raw)
In-Reply-To: <20100217200426.13409.32688.stgit@case>

This is the commit_metadata export operation for XFS.

- Takes one inode to be committed.

- Forces the log up to the lsn of the inode.

- Doesn't force the log if the inode doesn't have a pincount.
