md: load/store badblock list from v1.x metadata

2011-07-28T01:31:47+00:00

Space must have been allocated when array was created.
A feature flag is set when the badblock list is non-empty, to
ensure old kernels don't load and trust the whole device.

We only update the on-disk badblocklist when it has changed.
If the badblocklist (or other metadata) is stored on a bad block, we
don't cope very well.

If metadata has no room for bad block, flag bad-blocks as disabled,
and do the same for 0.90 metadata.

1/ Raid5 has learned to take over also raid4 and raid6 arrays.
2/ new_chunk in mdp_superblock_1 is in sectors, not bytes.

md/raid6: move raid6 data processing to raid6_pq.ko

2009-03-31T04:09:39+00:00

Move the raid6 data processing routines into a standalone module
(raid6_pq) to prepare them to be called from async_tx wrappers and other
non-md drivers/modules.  This precludes a circular dependency of raid456
needing the async modules for data processing while those modules in
turn depend on raid456 for the base level synchronous raid6 routines.

To support this move:
1/ The exportable definitions in raid6.h move to include/linux/raid/pq.h
2/ The raid6_call, recovery calls, and table symbols are exported
3/ Extra #ifdef __KERNEL__ statements to enable the userspace raid6test to
   compile

md: move md_k.h from include/linux/raid/ to drivers/md/

md: move lots of #include lines out of .h files and into .c

2009-03-31T03:33:13+00:00

This makes the includes more explicit, and is preparation for moving
md_k.h to drivers/md/md.h

Remove include/raid/md.h as its only remaining use was to #include
other files.

md: move most content from md.h to md_k.h

2009-03-31T03:33:13+00:00

The extern function definitions are kernel-internal definitions, so
they belong in md_k.h

The MD_*_VERSION values could reasonably go in a number of places,
but md_u.h seems most reasonable.

This leaves almost nothing in md.h.  It will go soon.

md: move LEVEL_* definition from md_k.h to md_u.h

.. as they are part of the user-space interface.
Also move MdpMinorShift into there so we can remove duplication.

Lastly move mdp_major in.  It is less obviously part of the user-space
interface, but do_mounts_md.c uses it, and it is acting a bit like
user-space.
