Hi, I'd like to attend LSF (and the first day of Vault). As a DM maintainer I'm open to discussing anything DM related. In particular I'd like to at least have hallway track discussions with key people interested in DM multipath support for blk-mq devices. Keith Busch and I have gone ahead and implemented the bulk of this request-based DM support for blk-mq devices, see: https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-for-3.20-blk-mq But Bart says he is seeing inconsistent performance now that the code appears relatively stable. I'll continue analyzing this aspect of things and by the time LSF rolls around I hope the code to be sorted. Another topic we need to come to terms with is the state of XCOPY (whether the initial approach needs further work, etc) -- Mikulas Patocka reworked aspects of Martin's initial approach but it hasn't progressed upstream: https://www.redhat.com/archives/dm-devel/2014-October/msg00167.html -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
