2cc7a01f10 Change the vnode locking protocol of VOP_GETATTR() to request at least 
a shared lock.  Make all calls outside of file systems respect it.

The calls from file systems need review.

No objections from tech-kern.

75268cff3f make dm aware of physical sector sizes. 
For aggregates of multiple disks we use the largest sector size from
all disks. For standard power-of-2 sizes this is the same as the least
common multiple. We still require proper alignment of the targets in
the mapping table.

8f6ed30d57 Introduce struct pathbuf. This is an abstraction to hold a pathname 
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.

Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).

The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

fb8751aba4 Add support for DIOCCACHESYNC ioctl for dm devices. Add new sync function 
pointer to dm_target_t because that is the only part of dm which know real
block device. disk_ioctl_switch parses whole device table and for every
entry it calls particular sync routine which propagates DIOCCACHESYNC
to real disk.

While I was here implement some KNF fixes and remove unneeded symbols from
dm.h.

Problem reported on port-xen@ by Hugo Silva.

6fc9836341 Be sure to config_cfattach_attach() in dmattach(). 
Loosely based on patch from Brian Brombacher,
with other inspriation from vnd(4).

This should fix PR kern/42799.

b9ba4842ce Hook device-mapper to autoconf framework. Add dm_attach, dm_match and dm_detach 
routines used by autoconf users. Change dm_dev_remove_ioctl to call dm_detach.

This should be primary used by kernel to disable devices during shutdown of
system with nested disk devices.

f26bfe28da Revert my commit which have added knowledge about dm targets to libdevmapper, 
this breaks abstraction. Because only lvmtools/lvmlib and device-mapper can
have knowledge about target mapping and libdevmapper only passes requests
from lvmtools to kernel and back. Bump major library and driver version.
