While debugging issues with the VDS server I made the
driver use partition 2 to get at the whole disk since
this is the "whole disk" partition in the Sun disk
label.We really should use slice 0xff which really means
the whole physical disk in the VIO disk protocol.
Otherwise things won't work well on a disk image
that doesn't have a proper disk label on it.Signed-off-by: David S. Miller

There's a memory leak in the cciss driver.
in alloc_cciss_hba() we may leak sizeof(ctlr_info_t) bytes if a
call to alloc_disk(1 << NWD_SHIFT) fails.
This patch should fix the issue.Spotted by the Coverity checker.

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.[akpm@linux-foundation.org: build fixes]

Since we have to be able to handle MD updates, having an in-tree
set of data structures representing the MD objects actually makes
things more painful.The MD itself is easy to parse, and we can implement the existing
interfaces using direct parsing of the MD binary image.The MD is now reference counted, so accesses have to now take the
form:handle = mdesc_grab();
... operations on MD ...
mdesc_release(handle);
The only remaining issue are cases where code holds on to references
to MD property values. mdesc_get_property() returns a direct pointer
to the property value, most cases just pull in the information they
need and discard the pointer, but there are few that use the pointer
directly over a long lifetime. Those will be fixed up in a subsequent
changeset.A preliminary handler for MD update events from domain services is
there, it is rudimentry but it works and handles all of the reference
counting. It does not check the generation number of the MDs,
and it does not generate a "add/delete" list for notification to
interesting parties about MD changes but that will be forthcoming.Signed-off-by: David S. Miller

bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl
commands. scsi_cmd_ioctl() gets a request queue from a gendisk
arguement. This prevents bsg being bound to SCSI devices that don't
have a gendisk (like OSD). This adds a request_queue argument to
scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so
it's safe for any SCSI devices to use scsi_cmd_ioctl().Signed-off-by: FUJITA Tomonori
