Thanks, Alasdair ---------------------------------------------------------------- Add a device-mapper target called dm-switch to provide a multipath framework for storage arrays that dynamically reconfigure their preferred paths for different device regions. Fix a bug in the verity target that prevented its use with some specific sizes of devices. Improve some locking mechanisms in the device-mapper core and bufio. Add Mike Snitzer as a device-mapper maintainer. A few more clean-ups and fixes. ---------------------------------------------------------------- Alasdair G Kergon (2): dm flakey: correct ctr alloc failure mesg dm: update maintainers Hannes Reinecke (1): dm mpath: fix ioctl deadlock when no paths Jim Ramsay (1): dm: add switch target Mikulas Patocka (9): dm ioctl: set noio flag to avoid __vmalloc deadlock dm verity: fix inability to use a few specific devices sizes dm: use __GFP_HIGHMEM in __vmalloc dm verity: remove pointless comparison dm verity: use __ffs and __fls dm cache: fix arm link errors with inline dm bufio: submit writes outside lock dm: optimize use SRCU and RCU dm: optimize reorder structure Documentation/device-mapper/switch.txt | 126 ++++++++ MAINTAINERS | 2 + drivers/md/Kconfig | 14 + drivers/md/Makefile | 1 + drivers/md/dm-bufio.c | 75 ++++- drivers/md/dm-cache-target.c | 4 + drivers/md/dm-flakey.c | 2 +- drivers/md/dm-ioctl.c | 127 +++++--- drivers/md/dm-mpath.c | 8 +- drivers/md/dm-switch.c | 538 ++++++++++++++++++++++++++++++++ drivers/md/dm-table.c | 35 --- drivers/md/dm-verity.c | 17 +- drivers/md/dm.c | 177 ++++++----- include/linux/device-mapper.h | 6 +- include/uapi/linux/dm-ioctl.h | 4 +- 15 files changed, 951 insertions(+), 185 deletions(-) create mode 100644 Documentation/device-mapper/switch.txt create mode 100644 drivers/md/dm-switch.c
