The 'devel3' was just a temporary branch I was using during development. I've since staged all the changes in linux-next via linux-dm.git's 'for-next' branch: https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/log/?h=for-next If you could test this 'for-next' and report back I'd appreciate it. It'd build my confidence in pushing these changes once the 4.6 merge window opens. That said, these changes have held up to Junichi's test suite. WHich I've now staged here (until I get around to porting them over to device-mapper-test-suite): https://github.com/snitm/mptest As for code review, please have a good look at this commit: b3c39bf1d dm mpath: convert from spinlock to RCU for most locking If you find anything feel free to share an incremental fix and I'll get it reviewed/staged. (Junichi I'd welcome your review of all these request-based DM core and multipath changes too) Thanks, Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
