NeilBrown 14f8d26b8e [PATCH] md: small cleanups for raid5
Resync code:
  A test that isn't needed,
  a 'compute_block' that makes more sense
    elsewhere (And then doesn't need a test),
  a couple of BUG_ONs to confirm the change makes sense.

Printks:
  A few were missing KERN_*

Also fix a typo in a comment..

NeilBrown 0a27ec96b6 [PATCH] md: improve raid10 "IO Barrier" concept
raid10 needs to put up a barrier to new requests while it does resync or other
background recovery.  The code for this is currently open-coded, slighty
obscure by its use of two waitqueues, and not documented.

This patch gathers all the related code into 4 functions, and includes a
comment which (hopefully) explains what is happening.

Darrick J. Wong ac81b2ee45 [PATCH] make dm-mirror not issue invalid resync requests
I've been attempting to set up a (Host)RAID mirror with dm_mirror on
2.6.14.3, and I've been having a strange little problem.  The configuration
in question is a set of 9GB SCSI disks that have 17942584 sectors.  I set
up the dm_mirror table as such:

0 17942528 mirror core 2 2048 nosync 2 8:48 0 8:64 0

If I'm not mistaken, this sets up a 9GB RAID1 mriror with 1MB stripes
across both SCSI disks.  The sector count of the dm device is less than the
size of the disks, so we shouldn't fall off the end.  However, I always get
the messages like this in dmesg when I set up the dm table:

attempt to access beyond end of device
sdd: rw=0, want=17958656, limit=17942584

Clearly, something is trying to read sectors past the end of the drive.  I
traced it down to the __rh_recovery_prepare function in dm-raid1.c, which
gets called when we're putting the mirror set together.  This function
calls the dirty region log's get_resync_work function to see if there's any
resync that needs to be done, and queues up any areas that are out of sync.
 The log's get_resync_work function is actually a pointer to the
core_get_resync_work function in dm-log.c.

The core_get_resync_work function queries a bitset lc->sync_bits to find
out if there are any regions that are out of date (i.e.  the bit is 0),
which is where the problem occurs.  If every bit in lc->sync_bits is 1
(which is the case when we've just configured a new RAID1 with the nosync
option), the find_next_zero_bit does NOT return the size parameter
(lc->region_count in this case), it returns the size parameter rounded up
to the nearest multiple of 32!  I don't know if this is intentional, but
i386 and x86_64 both exhibit this behavior.

In any case, the statement "if (*region == lc->region_count)" looks like
it's supposed to catch the case where are no regions to resync and
return 0.  Since find_next_zero_bit apparently has a habit of returning
a value that's larger than lc->region_count, the enclosed patch changes
the equality test to a greater-than test so that we don't try to resync
areas outside of the RAID1 region.  Seeing as the HostRAID metadata
lives just past the end of the RAID1 data, mucking around in that area
is not a good idea.

I suppose another way to fix this would be to amend find_next_zero_bit so
that it doesn't return values larger than "size", but I don't know if
there's a reason for the current behavior.

Frank Pavlic 8129ee1642 [PATCH] s390: qdio V=V pass-through
New feature V=V qdio pass-through.

QDIO and HiperSockets processing in z/VM V=V guest environments (as well as
V=R with z/VM running in LPAR mode) requires shadowing of all QDIO
architecture queue elements.  Especially the shadowing of SBALs and SLSBs
structures in the hypervisor, and the need to issue SIGA SYNC operations to
observe state changes, eventually causes significant CPU processing overhead
in the hypervisor.

The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and
SLSBs.  This significantly reduces the hypervisor overhead for QDIO based I/O.

Horst Hummel 1c01b8a596 [PATCH] s390: dasd failfast support
To properly support multipath-failover handling, the linux block layer has
introduced a special request flag, 'REQ_FAILFAST'.  This flag is now used to
return requests immediately in case the device is not operational.

Horst Hummel 9a7af28966 [PATCH] s390: BIODASDPRRD ioctl return code
The IOCTL BIODASDPRRD had no return code for 'profiling is inactive' and
therefore tunedasd wrote misleading message for request-counter = 0.
Introduce return-code EIO for inactive profiling.

Extract the s390_root_dev_* functions from the common I/O layer as they are
also used by non-ccw device drivers.

Cornelia Huck 6810a2bce3 [PATCH] s390: re-activated path detection
If we receive path not operational indications (pnom in pmcw nonzero), we
switch off those paths.  To catch them becoming available again, we have to
recalculate the lpm from the pmcw each time we start path verification.
