Subject: Log symlink creation
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=3cdb8dde718a6da64ba11d02774a934de40728fe;p=LaFS.git

Log symlink creation

We cannot include it in an update, so just make sure it goes in the
next write cluster.  This will be before an sync or fsync and
roll-forward should pick it up, so all is OK
