and do them correctly.

If you're going to change the name of something, you need to change
the name of *all* the things with the same name, not just a handful,
and you should change it to something similar so it still matches the
rest of the system rather than just picking an arbitrarily different
name.

Hi, Joerg.

To wit, rename the quotactl "delete" operation to "del", because
"delete" is a reserved word in C++ and for some reason Joerg wants to
run internal interfaces used only by C code through his C++ compiler.
Do not rename it to "remove" instead, because this doesn't match
libquota or the rest of the usage throughout the system; and rename
all the related identifiers, not just the ones that blew the mind of
Joerg's C++ compiler.

Because this is not a user-facing API (the only userland consumer
sys/quotactl.h is libquota) it is sort of ok to make arbitrary
source-incompatible changes; however, by the same token it's completely
unnecessary. If it *were* a user-facing API that someone might have a
semi-rational reason to want to run a C++ compiler on, it would be
incorrect to change it at this point.

Don't t use a C++ keyword as field name.

fix typo; hi christos

This is now equivalent to ufs_quota.c -r1.115.

(it isn't quite the same textually in a few places but this doesn't
really matter)

fix unused variable warnings

Migrate the miscellaneous ulfs-level info from struct ulfsmount to
struct lfs.

Put them inside #ifdef _KERNEL there. They are not the only such
members, gross as that is. Unfortunately, moving struct lfs to
lfs_kernel.h does not work.

branches: 1.6.2; 1.6.4;
Cleanups and hacks to make lfs userland stuff build:
- lfs_cksum.c doesn't actually need ulfs_inode.h any more.
- neither does lfs_itimes.c.
- add hacks to fsck_lfs to make it compile.
- add hacks to newfs_lfs to make it compile.
- fix warning in ulfs_quota.c when quotas are fully disabled
(as I guess is happening with the rumpity version)

XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for
XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned
XXX: up ASAP; but I consider this less problematic in the short term
XXX: than spewing ulfs_*.h into /usr/include.

Add lfs_ or ulfs_ in front of extern symbols lacking them, mostly
quota-related (and particularly quota2-related) stuff.

Split lfs from ufs step 4:

Massedit all ufs symbols to be "ulfs" instead, to make sure there are
no conflicts with ufs. Confirmed with grep.

(This required changing a few comments that maybe should have been
left alone to say "ulfs", but we'll survive that.)

Split lfs from ufs step 3: rearrange config stuff.
Add new options:
LFS_EI
LFS_DIRHASH
LFS_EXTATTR
LFS_EXTATTR_AUTOSTART
LFS_QUOTA
LFS_QUOTA2

and update code referring to the corresponding FFS and UFS config
symbols to use the LFS versions. Disable the one extant reference
to APPLE_UFS in the ulfs files. Use opt_lfs.h only, not opt_ffs.h.

Split lfs from ufs, part 2:

Change all <ufs/ufs/foo.h> includes to <ufs/lfs/ulfs_foo.h>.

Split lfs from ufs, part 1: cut and paste 15000 lines of ufs as "ulfs".

These are verbatim copies except that I've preserved the ufs rcsids
for reference. Also,
ufs/quota.h -> ulfs_quotacommon.h
ufs/ufs_quota.h -> ulfs_quota.h

Splitting lfs from ufs was ok'd by core some years ago. This is not
from my original tree, which became unmergeable after the several sets
of quota changes; I've done the work over again over the last couple
days.
