Hi Linus,
I rebased the DM tree ontop of linux-block.git's 'for-3.18/core' at the
beginning of October because DM core now depends on the newly introduced
bioset_create_nobvec() interface.
The following changes since commit d8f429e1669b9709f5b669aac9d734dbe0640891:
block: add bioset_create_nobvec() (2014-10-03 15:28:18 -0600)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/dm-3.18
for you to fetch changes up to 56ec16cb1e1ce46354de8511eef962a417c32c92:
dm log userspace: fix memory leak in dm_ulog_tfr_init failure path (2014-10-05 20:03:38 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
. fix DM's long-standing excessive use of memory by leveraging the new
bioset_create_nobvec() interface when creating the DM's bioset
. fix a few bugs in dm-bufio and dm-log-userspace
. add DM core support for a DM multipath use-case that requires loading
DM tables that contain devices that have failed (by allowing active
and inactive DM tables to share dm_devs)
. add discard support to the DM raid target; like MD raid456 the user
must opt-in to raid456 discard support be specifying the
devices_handle_discard_safely=Y module param.
