Alasdair, I've reviewed all of these patches from Jon: - cleaned up all patch headers and subjects a bit - patch 1 is a fix that should go to 2.6.37 - the others are fine to go to linux-next (and queue for 2.6.38) - made some changes to patch 3 (uninit 'type' warning, move 'group' from end of 'log_c' structure to flush_by_group's stack). Jon may clean up the flush_by_group() list processing further but I've added a useful comment about the final list_splice_init. Thanks, Mike Jonathan Brassow (4): dm log userspace: trap all errors from failed log construction dm log userspace: split flush queue dm log userspace: group clear and mark requests dm log userspace: add version number to communication structure drivers/md/dm-log-userspace-base.c | 130 ++++++++++++++++++++++++++------ drivers/md/dm-log-userspace-transfer.c | 1 + include/linux/dm-log-userspace.h | 13 +++- 3 files changed, 119 insertions(+), 25 deletions(-) -- 1.7.2.3 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
