scheme. The LDM is a logical volume manager for MS Windows NT and it
is also known as dynamic volumes. It supports about 2000 partitions
and also provides the capability for software RAID implementations.
This version implements only partitioning scheme capability and based
on the linux-ntfs project documentation and several publications across
the Web. NOTE: JBOD, RAID0 and RAID5 volumes aren't supported.
An access to the LDM metadata is read-only. When LDM is on the disk
partitioned with MBR we can also destroy metadata. For the GPT
partitioned disks destroy action is not supported.

that pv_table is sized for non-fictitious pages only.
Consistently check for the page to be non-fictitious before accesing

With the current API (no *at functions), FTS_NOCHDIR requires that the
fts_accpath start with the original path passed to fts_open(); therefore,
the depth that can be reached is limited by the {PATH_MAX} constraint on
this pathname.

The tREGISTER macros are only made visible on i386. These macros are
deprecated and should not be available on amd64.
The i386 and amd64 versions of struct reg have been renamed to struct
__reg32 and struct __reg64. During compilation either __reg32 or __reg64
is defined as reg depending on the machine architecture. On amd64 the i386
struct is also available as struct reg32 which is used in COMPAT_FREEBSD32
code.
Most of compat/ia32/ia32_reg.h is now IA64 only.

manipulation of the pvo_vlink and pvo_olink entries is already protected
by the table lock, so most remaining instances of the acquisition of the
page queues lock can likely be replaced with the table lock, or removed
if the table lock is already held.

RT_NUMFIBS into the implemantion to avoid further usage in other
code. rt_numfibs is all that should be needed.
This allows users to change the number of FIBs from 1..RT_MAXFIBS(16)
dynamically using the tunable without the need to change the kernel
config for the maximum anymore. This means that thet multi-FIB
feature is now fully available with GENERIC kernels.
The kernel option ROUTETABLES can still be used to set the default
numbers of FIBs in absence of the tunable.

They think a previous lock holder should have already left the mutex and
is no longer referencing it, so they destroy it. To be maximum compatible
with such code, we use IA64 version to unlock the mutex in kernel, remove
