Commit 4257e08 ("dm raid: support to change bitmap region size")
introduced a bitmap resize call during preresume phase. User can create
a DM device with "raid" target configured as raid1 with no metadata
devices to hold superblock/bitmap info. It can be achieved using the
following sequence:
truncate -s 32M /dev/shm/raid-test
LOOP=$(losetup --show -f /dev/shm/raid-test)
dmsetup create raid-test-linear0 --table "0 1024 linear $LOOP 0"
dmsetup create raid-test-linear1 --table "0 1024 linear $LOOP 1024"
dmsetup create raid-test --table "0 1024 raid raid1 1 2048 2 - /dev/mapper/raid-test-linear0 - /dev/mapper/raid-test-linear1"
This results in the following crash:

The raid_preresume() function incorrectly assumes that the raid_set has
a bitmap enabled if RT_FLAG_RS_BITMAP_LOADED is set. But
RT_FLAG_RS_BITMAP_LOADED is getting set in __load_dirty_region_bitmap()
even if there is no bitmap present (and bitmap_load() happily returns 0
even if a bitmap isn't present). So the only way forward in the
near-term is to check if the bitmap is present by seeing if
mddev->bitmap is not NULL after bitmap_load() has been called.
By doing so the above NULL pointer is avoided.

This version bump reflects that the reshape corruption fix (commit
92a39f6cc "dm raid: fix data corruption on reshape request") is
present.
Done as a separate fix because the above referenced commit is marked for
stable and target version bumps in a stable@ fix are a recipe for the
fix to never get backported to stable@ kernels (because of target
version number conflicts).
Also, move RESUME_STAY_FROZEN_FLAGS up with the reset the the _FLAGS
definitions now that we don't need to worry about stable@ conflicts as a
result of missing context.

The lvm2 sequence to manage dm-raid constructor flags that trigger a
rebuild or a reshape is defined as:
1) load table with flags (e.g. rebuild/delta_disks/data_offset)
2) clear out the flags in lvm2 metadata
3) store the lvm2 metadata, reload the table to reset the flags
previously established during the initial load (1) -- in order to
prevent repeatedly requesting a rebuild or a reshape on activation
Currently, loading an inactive table with rebuild/reshape flags
specified will cause dm-raid to rebuild/reshape on resume and thus start
updating the raid metadata (about the progress). When the second table
reload, to reset the flags, occurs the constructor accesses the volatile
progress state kept in the raid superblocks. Because the active mapping
is still processing the rebuild/reshape, that position will be stale by
the time the device is resumed.
In the reshape case, this causes data corruption by processing already
reshaped stripes again. In the rebuild case, it does _not_ cause data
corruption but instead involves superfluous rebuilds.
Fix by keeping the raid set frozen during the first resume and then
allow the rebuild/reshape during the second resume.

While cleaning up awkward branching in raid_message() a raid set "check"
regression was introduced because "check" needs both MD_RECOVERY_SYNC
and MD_RECOVERY_REQUESTED flags set.
Fix this regression by explicitly setting both flags for the "check"
case (like is also done for the "repair" case, but redundant set_bit()s
are perfectly fine because it adds clarity to what is needed in response
to both messages -- in addition this isn't fast path code).

Add md raid4/5/6 journaling support (upstream commit bac624f3f86a started
the implementation) which closes the write hole (i.e. non-atomic updates
to stripes) using a dedicated journal device.
Background:
raid4/5/6 stripes hold N data payloads per stripe plus one parity raid4/5
or two raid6 P/Q syndrome payloads in an in-memory stripe cache.
Parity or P/Q syndromes used to recover any data payloads in case of a disk
failure are calculated from the N data payloads and need to be updated on the
different component devices of the raid device. Those are non-atomic,
persistent updates. Hence a crash can cause failure to update all stripe
payloads persistently and thus cause data loss during stripe recovery.
This problem gets addressed by writing whole stripe cache entries (together with
journal metadata) to a persistent journal entry on a dedicated journal device.
Only if that journal entry is written successfully, the stripe cache entry is
updated on the component devices of the raid device (i.e. writethrough type).
In case of a crash, the entry can be recovered from the journal and be written
again thus ensuring consistent stripe payload suitable to data recovery.
Future dependencies:
once writeback caching being worked on to compensate for the throughput
implictions involved with writethrough overhead is supported with journaling
in upstream, an additional patch based on this one will support it in dm-raid.
Journal resilience related remarks:
because stripes are recovered from the journal in case of a crash, the
journal device better be resilient. Resilience becomes mandatory with
future writeback support, because loosing the working set in the log
means data loss as oposed to writethrough, were the loss of the
journal device 'only' reintroduces the write hole.
Fix comment on data offsets in parse_dev_params() and initialize
new_data_offset as well.

During raid set resize checks and setting up the recovery offset in case a raid
set grows, calculated rd->md.dev_sectors is compared to rs->dev[0].rdev.sectors.
Device 0 may not be defined in case userspace passes in '- -' for it
(lvm2 doesn't do that so far), thus it's device sectors can't be taken
authoritatively in this comparison and another valid device must be used
to retrieve the device size.
Use mddev->dev_sectors in checking for ongoing recovery for the same reason.

This fix addresses the following 3 failure scenarios:
1) If a (transiently) inaccessible metadata device is being passed into the
constructor (e.g. a device tuple '254:4 254:5'), it is processed as if
'- -' was given. This erroneously results in a status table line containing
'- -', which mistakenly differs from what has been passed in. As a result,
userspace libdevmapper puts the device tuple seperate from the RAID device
thus not processing the dependencies properly.
2) False health status char 'A' instead of 'D' is emitted on the status
status info line for the meta/data device tuple in this metadata device
failure case.
3) If the metadata device is accessible when passed into the constructor
but the data device (partially) isn't, that leg may be set faulty by the
raid personality on access to the (partially) unavailable leg. Restore
tried in a second raid device resume on such failed leg (status char 'D')
fails after the (partial) leg returned.
Fixes for aforementioned failure scenarios:
- don't release passed in devices in the constructor thus allowing the
status table line to e.g. contain '254:4 254:5' rather than '- -'
- emit device status char 'D' rather than 'A' for the device tuple
with the failed metadata device on the status info line
- when attempting to restore faulty devices in a second resume, allow the
device hot remove function to succeed by setting the device to not in-sync
In case userspace intentionally passes '- -' into the constructor to avoid that
device tuple (e.g. to split off a raid1 leg temporarily for later re-addition),
the status table line will correctly show '- -' and the status info line will
provide a '-' device health character for the non-defined device tuple.

The mddev->flags are used for different purposes. There are a lot of
places we check/change the flags without masking unrelated flags, we
could check/change unrelated flags. These usage are most for superblock
write, so spearate superblock related flags. This should make the code
clearer and also fix real bugs.

Remove CTR_FLAG_MAX_WRITE_BEHIND from raid4/5/6's valid ctr flags.
Only the md raid1 personality supports setting a maximum number
of "write behind" write IOs on any legs set to "write mostly".
"write mostly" enhances throughput with slow links/disks.
Technically the "write behind" value is a write intent bitmap
property only being respected by the raid1 personality. It allows a
maximum number of "write behind" writes to any "write mostly" raid1
mirror legs to be delayed and avoids reads from such legs.
No other MD personalities supported via dm-raid make use of "write
behind", thus setting this property is superfluous; it wouldn't cause
harm but it is correct to reject it.

The raid0 MD personality does not start a raid0 array with any of its
data devices missing.
dm-raid was removing data/metadata device pairs unconditionally if it
failed to read a superblock off the respective metadata device of such
pair, resulting in failure to start arrays with the raid0 personality.
Avoid removing any data/metadata device pairs in case of raid0
(e.g. lvm2 segment type 'raid0_meta') thus allowing MD to start the
array.
Also, avoid region size validation for raid0.
