md: Add module.h to all files using it implicitly

2011-10-31T23:31:18+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in md dir
are actually calling out for  explicitly in advance.

dm: raid fix device status indicator when array initializing

2011-10-31T20:21:26+00:00

When devices in a RAID array are not in-sync, they are supposed to be
reported as such in the status output as an 'a' character, which means
"alive, but not in-sync".  But when the entire array is rebuilt 'A' is
being used, which is incorrect.  This patch corrects this to 'a'.

md: remove typedefs: mddev_t -> struct mddev

2011-10-11T05:47:53+00:00

Having mddev_t and 'struct mddev_s' is ugly and not preferred

md: removing typedefs: mdk_rdev_t -> struct md_rdev

2011-10-11T05:45:26+00:00

The typedefs are just annoying. 'mdk' probably refers to 'md_k.h'
which used to be an include file that defined this thing.

dm: raid fix write_mostly arg validation

2011-09-25T22:26:19+00:00

Fix off-by-one error in validation of write_mostly.

The user-supplied value given for the 'write_mostly' argument must be an
index starting at 0.  The validation of the supplied argument failed to
check for 'N' ('>' vs '>='), which would have caused an access beyond the
end of the array.
