Unless I'm missing something, I don't think there's any reason these all need to be bundled together. Further, my expectation is that they probably end up being merged as independent units, so I think it's easier for everybody for Darrick to carve that up on the logical boundaries rather than assume all reviewers and maintainer are going to do so consistently. Note that I'm not saying this has to be reposted.. I think I can pull off the rmap bits for the time being. I'm just suggesting that if a repost is required from this point forward for any of the logical subunits (deps, rmap, reflink, scrub), I'd suggest to post, version and changelog those units independently.

Yes, that's what I meant. I just didn't manage to get to the rest yet. > off the rmap bits for the time being.

I'd thought about continuing my old practice of listing which patches go with which feature... but then got lazy. :( Cleanups/rmap/reflink/scrub actually are in their own contiguous sections of the patchbomb, though that isn't obvious from looking at it. You ought to be able to pull only as far as the end of the rmap series and still have a working XFS. I only did the intensive testing with the full patchset, but the quick xfstests group ran fine with just the rmap pieces.

I was able to surmise where the rmap stuff ends. It's not so clear where the line between cleanups vs. dependencies is, however, and as hch mentioned, some of that stuff apparently stands on its own (i.e, can be merged without being blocked on rmap review/test/dev cycles). > You ought to be able to pull only as far as the end of the rmap series and > still have a working XFS.

I still stand by my previous comment wrt to splitting any subsequent postings, if necessary, into separate series though. ;) Brian > reflink + dependencies, 50-111 > AG reservations, 50-52 > refcount btree, 53-68 > deferred remap, 69-73 > cow, 74-88 > reflink, 89-111 > getfsmapx, 112 > scrub, 113-119 > > xfsprogs: > ========= > Cleanups, 1-15 > rmap + deps, 16-70 > Overlapped interval btree, 16-19 > Deferred operations, 20-27 > rmap, 28-70 > reflink + dependencies, 71-135 > AG reservations, 71-72 > refcount btree, 73-85 > deferred remap, 86-90 > reflink, 91-135 > getfsmapx, 136-138 > scrub, 139-145 > > --D > > > > > Brian > > > > > _______________________________________________ > > > xfs mailing list > > > xfs@oss.sgi.com > > > http://oss.sgi.com/mailman/listinfo/xfs > > _______________________________________________ > xfs mailing list > xfs@oss.sgi.com > http://oss.sgi.com/mailman/listinfo/xfs -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
