to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

afterwards. Fixes newfs_msdos at least on sparc. Incidentally,
the msdosfs tests also start working on sparc, which about halves
the number of test failures on that platform.
"FSS_UNLINK_ON_CREATE" to unlink the backing store before
the snapshot gets created.
With this change dump(8) no longer dumps the zero-sized, but named
snapshot it is working on. Same applies to fsck_ffs(8).
for some reason. (But I have no idea why that would be -- if you have one
of these really ancient partitions and you're about to run disklabel, you
can easily run fdisk first and change the partition type to NetBSD.)
As it stands, the code will munch FreeBSD installs under some
circumstances, which is really not acceptable behavior.
The code, along with the kernel support that's been disabled by
default for several years, and some related but less dangerous code in
sysinst, should prboably be removed entirely after -6 is branched.
Discussed on tech-kern and tech-userlevel; closes PR 44496.
This is also almost certainly the cause of PR 42521 and PR 38841.
to access, manage and manipulate device-mapper driver. Which opens us bunch
of new possibilities like
dm-multipath device target
dm-crypt device target
dm-ccd compatibility layer
With this import I'm bringing in dmctl tool for working with dm driver ,too.
I plan to replace gpl2 licensed dmsetup command with our dmctl tool in near
feature. It can also by placed to /rescue where we was not able to put
dmsetup because of licensing problems.
With libdm in tree we can now write RUMP atf test suite for dm driver to
ensure LVM subsystem stability as time goes.

While I'm here, reformat the code for closer adherence to KNF.
