[PATCH nbdkit 2/2] filters: Be careful to set *err if nbdkit_add_extent or nbdkit_extents_new fail.
This fix isn't exhaustive but it fixes some obvious problems in the filters. Rich.

[nbdkit PATCH 0/4] Start using cleanup macros in filters/plugins
There's more that can be done (in particular, use of CLEANUP_FREE), but this is enough to at least see if I'm on the right track. I couldn't figure out an obvious difference between common/include and common/utils, but it looks like the former is for things that are inlineable via .h only, while the latter is when you need to link in a convenience library, so this landed in the

[PATCH nbdkit 0/8] Implement extents using a simpler array.
Not sure what version we're up to, but this reimplements extents using the new simpler structure described in this thread: https://www.redhat.com/archives/libguestfs/2019-March/msg00077.html I also fixed most of the things that Eric pointed out in the previous review, although I need to go back over his replies and check I've got everything. This needs a bit more testing. However the

[PATCH nbdkit v4 00/15] Implement Block Status.
I'm not sure exactly which version we're up to, but let's say it's version 4. I'm a lot happier with this version: - all filters have been reviewed and changed where I think that's necessary - can_extents is properly defined and implemented now - NBD protocol is followed - I believe it addresses all previous review points where possible The "only" thing

[PATCH nbdkit 0/9] [mainly for discussion and early review] Implement extents.
I want to post this but mainly for discussion and early review. It's not safe for these patches to all go upstream yet (because not all filters have been checked/adjusted), but if any patches were to go upstream then probably 1 & 2 only are safe. File, VDDK, memory and data plugins all work, although I have only done minimal testing on them. The current tests, such as they are, all

[nbdkit PATCH v2 00/24] implement NBD_CMD_CACHE
Since v1: - rework .can_cache to be tri-state, with default of no advertisement (ripple effect through other patches) - add a lot more patches in order to round out filter support And in the meantime, Rich pushed NBD_CMD_CACHE support into libnbd, so in theory we now have a way to test cache commands through the entire stack.

[PATCH nbdkit v5 FINAL 00/19] Implement extents.
This has already been pushed upstream. I am simply posting these here so we have a reference in the mailing list in case we find bugs later (as I'm sure we will - it's a complex patch series). Great thanks to Eric Blake for tireless review on this one. It also seems to have identified a few minor bugs in qemu along the way. Rich.
