Merge tag 'dm-3.8-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm
Pull dm update from Alasdair G Kergon: "Miscellaneous device-mapper fixes, cleanups and performance improvements. Of particular note: - Disable broken WRITE SAME support in all targets except linear and striped. Use it when kcopyd is zeroing blocks. - Remove several mempools from targets by moving the data into the bio's new front_pad area(which dm calls 'per_bio_data'). - Fix a race in thin provisioning if discards are misused. - Prevent userspace from interfering with the ioctl parameters and use kmalloc for the data buffer if it's small instead of vmalloc. - Throttle some annoying error messages when I/O fails." * tag 'dm-3.8-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm: (36 commits) dm stripe: add WRITE SAME support dm: remove map_info dm snapshot: do not use map_context dm thin: dont use map_context dm raid1: dont use map_context dm flakey: dont use map_context dm raid1: rename read_record to bio_record dm: move target request nr to dm_target_io dm snapshot: use per_bio_data dm verity: use per_bio_data dm raid1: use per_bio_data dm: introduce per_bio_data dm kcopyd: add WRITE SAME support to dm_kcopyd_zero dm linear: add WRITE SAME support dm: add WRITE SAME support dm: prepare to support WRITE SAME dm ioctl: use kmalloc if possible dm ioctl: remove PF_MEMALLOC dm persistent data: improve improve space map block alloc failure message dm thin: use DMERR_LIMIT for errors ...
