This is pass 2 of the userspace side of the invalid metadata LSN fixes. It is based on the RFCv2 version of the associated kernel fixes: http://oss.sgi.com/pipermail/xfs/2015-September/043627.html Outside of the rebase to the latest kernel patch, this version adds support for the xfs_db uuid command and xfs_metadump. Both of these utilities clear the log under certain circumstances and thus both have been updated to format the log with a bumped cycle number when appropriate. The only remaining gap that I'm aware of is xfs_copy. xfs_copy support is not included because the log formatting code therein is slightly more complicated than what is done in other places. In particular, it uses its own buffer and alignment mechanisms that have to deal with direct I/O alignment rules and aren't easily compatible with the existing buffered log formatting mechanism. I haven't quite figured out how best to deal with that yet. Thoughts, reviews, flames appreciated.
