In the process: - GFS2, OCFS2 theoretically get nonlinear mapping support - Nonlinear mappings gain page_mkwrite and dirty page throttling support - Nonlinear mappings gain the fault vs truncate race fix introduced for linear All pretty much for free. This is lightly compile tested only, unlike the last set, mainly because it is presently just an RFC regarding the direction I'm going (and it's bedtime).
