Looking into the hairy metapage code in JFS I wonder if we should do the same. While JFS isn't anywhere as complicated as reiserfs, it's also way less used and never made it to be the default file system in any major distribution. It's also looking pretty horrible in xfstests, and with all the ongoing folio work and hopeful eventual phaseout of buffer head based I/O path it's going to be a bit of a drag. (Which also can be said for many other file system, most of them being a bit simpler, though).
