The XFS iolock needs to be re-initialised to a new lock class before it enters reclaim to prevent lockdep false positives. Unfortunately, this is not sufficient protection as inodes in the XFS_IRECLAIMABLE state can be recycled and not re-initialised before being reused. We need to re-initialise the lock state when transfering out of XFS_IRECLAIMABLE state to XFS_INEW, but we need to keep the same class as if the inode was just allocated. Hence we need a specific lockdep class variable for the iolock so that both initialisations use the same class. While there, add a specific class for inodes in the reclaim state so that it is easy to tell from lockdep reports what state the inode was in that generated the report.
