As --offroot causes ARGV[0] to be changed, we need to be more
lenient when checking that the mdmon we are about to kill really
is mdmon. i.e. allow name to be "@dmon" instead.

When adding a spare to a DDF there is some confusion about the
'level' of the container. It is reported by kernel as unknown
-1000000.
I don't know why this broke but until I figure out why and fix it,
this hack gets us going again.

If a DDF has two arrays sharing devices and one device fails, then
as soon as the spare is used to recover one of the arrays it isn't
spare any more and so is not chosen for the other array.
Work around this for now by allowing a non-spare to be used if it has
enough space.

'external' arrays don't support --re-add yet so old metadata is no
value, and 'ddf' gets confusing in mdmon if old metadata is found.
So for now, zero out any old metadata found before adding a spare to
an externally-managed array.

Since udev is moving its internal dir around, query it via pkg-config
rather than hardcoding the old path. This should work with new/old

The current Makefile ends up ignoring the system CPPFLAGS settings,
so make sure we append the variable. Also, the old metadata logic

Analogous changes should be made to reshape_super().

In the "add" uevent, ATTR{md/array_state} does not exist, so the next
rule does not kick in.
When an array is assembled incrementally, systemd might see it
before it is ready, try to mount it, fail, and give up.
Result is that array doesn't get mounted.
If we ask udev to tell systemd that it isn't ready yet in this
case, systemd waits until it is ready, and all are happy.

We need to set speed_limit_min accordingly, otherwise setting
speed_limit_max below 1000 will have no effect.
Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com>
Signed-off-by: NeilBrown <neilb@suse.de>
This test is quite sensitive to resync speed - if the resync happens
to quickly it fails because it sees aan optimal array when it expects
a degraded array.
1000 is often slow enough but now always, so slow it down even more.
This requires reducing speed_limit_min also as kernel ignores 'max'
when speed is below 'min'.

'st' is use to examine the metadata on the device being added
to see if a 're-add' is possible. However it is loaded long before
the 're-add' attempt is made.
So move the 'load_super' closer to were it is used - allowing us to
discard a number of 'free_super' call - and rename it to 'dev_st'
to emphasize that it related to the current device.

In repair mode, raid6check will rewrite one single stripe
by regenerating the data (or parity) of two raid devices that
are specified via the command line.
If you need to rewrite just one slot, pick any other slot
at random.
Note that the repair option will change data on the disks
directly, so both the md layer above as well as any layers
above md (such as filesystems) may be accessing the stripe
data from cached buffers. Either instruct the kernels
to drop the caches or reassemble the raid after repair.

We currently have rather hard-to-follow loop to iterate
through all the matches for 'missing' or 'faulty' or 'detached'.
Simplify it by creating a list of possible devices for each
of those and splicing the new list into the device list.
This removes the need for 'jnext' and 'next' and various other hacks.

Both are impossible, and '1' allows size to be unsigned,
which is neater.
Also #define MAX_SIZE to be '1' to make it all more explicit.

The value of 'verbose' is sometimes mixed into 'brief', particularly
for Examine.
This is messy and confusing. So keep them separate.
'brief' still gets assumed when 'scan' is set, unless we are very
verbose.

If we change some functions to accept 'verbose', where <0 means to be
quiet, in place of 'quiet', then we will be able to merge
