cap.max_inline_data is incorrectly set in init_attr instead of attr.
Set it in attr so subsequent init_attr.cap assignment will get the
correct value.

The intent here is to check the "mfrpl->mapped_page_list" allocation.
We checked "mfrpl->ibfrpl.page_list" earlier.

When manually assigning the path records to use for a connection, save
the number of paths that were set. Otherwise, checks against num_path
will show 0, even though path record data is available.
This was discovered by manually setting the path records from user
space, then querying the kernel to see if the correct path records
were assigned, only to discover that the kernel returned 0 path
records to the query.

"len" hasn't been properly range checked so we shouldn't use it as an
array offset. This can only be written to by root but it would still be
annoying to accidentally write more than 3 characters and corrupt your
memory.

Hi Jens,
I came across this recently - these are the only two occurances
of "GENHD_FL_DRIVERFS" in the kernel, so it cannot be needed.

Up to now, applying the in-core activity-log to the on-disk
bitmap did not care for logical_block_size.
On logical_block_size != 512 byte, this very likely results
in misalligned block access and spurious "io errors".
We now simply always submit aligned whole 4k blocks, fixing this
for logical block sizes of 512, 1024, 2048 and 4096.
For even larger logical block sizes, this won't work.
But I'm not aware of devices with such properties being available.

cmdname() should map command number to its human readable

Fixes a race and potential kernel panic if e.g. the worker was just
about to send a few P_RS_IS_IN_SYNC via the meta socket for checksum
based resync, while the receiver destroys the sockets in
drbd_disconnect.
To make sure no-one is using the meta socket,
it is not enough to stop the asender...
Grab the meta socket mutex before destroying it.

Depending on resync request size,
we need to account for more than one bit.
Impact: cosmetic
If SyncTarget reported correctly 100% equal checksums,
the SyncSource usually reported 12% equal checksums instead,
because it only counted requests, we typically do 32k resync requests,
and the bitmap granularity is still 4k.

Situation:
we have diverging data sets, i.e. we had a split brain somewhen,
but currently are connected, one node diskless.
Then we try to attach that disk, figure it is consistent,
but has a diverging data set, we refuse to attach.
This led to strange state changes:
22:18:35 bb drbd1: peer( Unknown -> Primary ) conn( WFReportParams -> Connected) pdsk( DUnknown -> UpToDate )
22:19:30 bb drbd1: disk( Diskless -> Attaching )

22:19:30 bb drbd1: Split-Brain detected, dropping connection!
22:19:30 bb drbd1: disk( Negotiating -> Diskless )
while the other side says:
22:19:30 aa drbd1: Split-Brain detected, dropping connection!
22:19:30 aa drbd1: Disk attach process on the peer node was aborted.
22:19:30 aa drbd1: conn( Connected -> TOO_LARGE ) pdsk( Diskless -> Consistent )
This should be fixed now.

This value interacts with some registers we don't currently know how to
program properly ourselves. The default of 5 that we were using matches
what the VBIOS on early DP cards do, but later ones use 6, which would
cause nouveau to program an incorrect mode on these chips.

All indications seem to be that the version 0x30 table should be handled
the same way as 0x40 (as used on G80), at least for the parts that we
currently try use.
This commit cleans up the parsing to make it clearer about what we're
actually trying to achieve, and unifies the 0x30/0x40 parsing.

As opposed to repeatedly reading the amount back from the GPU every
time we need to know the VRAM size.
We should now fail to load gracefully on detecting no VRAM, rather than
something potentially messy happening.

Previously we were filling it the same as "placements", but in some
cases there're valid alternatives that we were ignoring completely.
Keeping a back-up memory type helps on several low-mem situations.

Fixes the !vbo_fifo path in the 3D driver on certain chipsets. Still not
really any good idea of what exactly the magic achieves, but it makes
things work.
While we're at it, in the PCIEGART path, flush on unbinding also.
