Hi,
please queue the following branch to 4.7.
New features or user-visible changes:
* device delete by id, a v2 ioctl for device deletion (this was held back from
4.6 pull due to possibly related crashes that haven't appeared for a long
time)
* DUP allowed on multiple-device filesystem (help in case we want to go to
SINGLE from RAID1/.. but do not want to lose all redundancy while converting)
* GETFLAGS/SETFLAGS/GETVERSION ioctls work on 32bit
Developer-visible changes:
* definitions that are shared with userspace are moved to the uapi directory
Other:
* assorted bugfixes and cleanups
The branch is merged from several topic branches, grouped by functionality
or purpose. The patches have been in for-next, most of them for a few weeks at
least, tested together with Filipe's branch.
Thanks.
