\| \| * \| \| \| \|	md-cluster: make md-cluster also can work when compiled into kernel	Guoqing Jiang	2016-09-24

The md-cluster is compiled as module by default, if it is compiled by built-in way, then we can't make md-cluster works.

\| \| * \| \| \| \|	dm crypt: fix error with too large bios	Mikulas Patocka	2016-09-24

When dm-crypt processes writes, it allocates a new bio in crypt_alloc_buffer(). The bio is allocated from a bio set and it can have at most BIO_MAX_PAGES vector entries, however the incoming bio can be larger (e.g. if it was allocated by bcache). If the incoming bio is larger, bio_alloc_bioset() fails and an error is returned. To avoid the error, we test for a too large bio in the function crypt_map() and use dm_accept_partial_bio() to split the bio. dm_accept_partial_bio() trims the current bio to the desired size and asks DM core to send another bio with the rest of the data.

Move log_one_block()'s atomic_inc(&lc->io_blocks) before bio_alloc() to fix a bug that the target hangs if bio_alloc() fails. The error path does put_io_block(lc), so atomic_inc(&lc->io_blocks) must occur before invoking the error path to avoid underflow of lc->io_blocks.

When the corrupt_bio_byte feature was introduced it caused READ bios to no longer be errored with -EIO during the down_interval. This had to do with the complexity of needing to submit READs if the corrupt_bio_byte feature was used. Fix it so READ bios are properly errored with -EIO; doing so early in flakey_map() as long as there isn't a match for the corrupt_bio_byte feature.

I'm bundling them because they are interdependent, and it'll be easier to drop it on rebase later. 1. dm: allow a dm-fs-style device to be shared via dm-ioctl Integrates feedback from Alisdair, Mike, and Kiyoshi. Two main changes occur here: - One function is added which allows for a programmatically created mapped device to be inserted into the dm-ioctl hash table. This binds the device to a name and, optional, uuid which is needed by udev and allows for userspace management of the mapped device. - dm_table_complete() was extended to handle all of the final functional changes required for the table to be operational once called. 2. init: boot to device-mapper targets without an initr* Add a dm= kernel parameter modeled after the md= parameter from do_mounts_md. It allows for device-mapper targets to be configured at boot time for use early in the boot process (as the root device or otherwise). It also replaces /dev/XXX calls with major:minor opportunistically. The format is dm="name uuid ro,table line 1,table line 2,...". The parser expects the comma to be safe to use as a newline substitute but, otherwise, uses the normal separator of space. Some attempt has been made to make it forgiving of additional spaces (using skip_spaces()). A mapped device created during boot will be assigned a minor of 0 and may be access via /dev/dm-0. An example dm-linear root with no uuid may look like: root=/dev/dm-0 dm="lroot none ro, 0 4096 linear /dev/ubdb 0, 4096 4096 linear /dv/ubdc 0" Once udev is started, /dev/dm-0 will become /dev/mapper/lroot.

The defualt verity keyid is passed as a kernel command line argument veritykeyid=. The order of the dm-android-verity params have been reversed to facilitate the change. Old format example: dm="system none ro,0 1 android-verity Android:#7e4333f9bba00adfe0ede979e28ed1920492b40f /dev/mmcblk0p43" New formats supported: dm="system none ro,0 1 android-verity /dev/mmcblk0p43 Android:#7e4333f9bba00adfe0ede979e28ed1920492b40f" (or) dm="system none ro,0 1 android-verity /dev/mmcblk0p43" when veritykeyid= is set in the kernel command line.
