Hi Ming Lei, would you like to repost these patches now that MQ support is in the kernel? Also, I changed my mind about moving linux-aio to AioContext. I now think it's a good idea, because it limits the number of io_getevents syscalls. O:-) So I would be happy to review your patches for that as well. Paolo

Eric Blake (4): server: Fix regression for NBD_OPT_INFO before NBD_OPT_GO server: Fix back-to-back SET_META_CONTEXT server: Forbid NUL in export and context names server: Fix OPT_GO on different export than SET_META_CONTEXT

This is a cover letter to a series of patches being proposed in tandem to four different projects: - nbd: Document a new NBD_CMD_FLAG_FAST_ZERO command flag - qemu: Implement the flag for both clients and server - libnbd: Implement the flag for clients - nbdkit: Implement the flag for servers, including the nbd passthrough client If you want to test the patches together, I've pushed a
