in procfs_allocvp(). This fixes at least stat() of /proc/*/mem.
stat() of /proc/*/file already worked. I think procfs_allocvp() isn't
actually called for type Pfile.
formula uses `& nchash'. This is very broken when nchash is a prime
number instead of 1 less than a power of 2, but the Lite2 formula was
merged in.
Merged some cosmetic changes from Lite2, rev.1.21 and Lite1. The merge
was difficult because the Lite2 code is essentially ours (phk's) except
where Lite2 improved or broke it.
Summary of the Lite2 changes:
- in the copyright, phk's rights have been transferred to the Regents.
This change should be reviewed.
- nchENOENT went away; the "no" vnode is now simply 0.
- comments were improved.
- style was "improved".
- goto instead of Fanatism (sic) was considered bad :-).
- there are some small changes to support whiteouts.
- new cache entries are added in more cases. More work is required
near here to change the hash table size if kern.desiredvnodes is
changed using sysctl.
- rescanning of the hash bucket in cache_purgevfs() was removed. This
change should be reviewed.
effect immediately, but required a following (normally redundant) G0
into GL mapping. This adds one layer of indirection (thus might make it
slower), but fixes the broken box character drawing in pcvt.
Hellmuth and Bruce are unfortunately too busy too review this right now,
but i wanna have it in 2.2 since it has often been asked in the past.
Warning: this won't work yet with PCVT_SCANSET=2 along in early
console mode (boot -c, or boot -d).
A big thanks to Kazutaka, and a word of apologies for delaying the
review for that long time...

Many things have been changing in the kernel since mid-1996, so there's
quite some amount of diffs here already. It compiles, but i cannot
test it anywhere here.
2.2 candidate?
Closes PR # 1201.
This is some of the worst code I've had to wade through in
ages and I don't want to have to start from scratch again next time.
(I have a 2.2 version of these comments, can I commit them?)
mount. This may have been a contributor to the 'null v_mount in
fsync()' problem
This is another, perhaps slightly less urgent, 2.2 last-minute candidate.

(phk's) sysctl framework, and I needed special code to disambiguate
the VFS_GENERIC node from the VFS_VFSCONF leaf, so I only converted
the leaves to the FreeBSD framework. The error handling isn't quite
right. CSRGS's sysctls seem to return ENOTDIR too much and FreeBSD's
sysctls don't agree with the man page.
instead of all hardcoded assumptions historically used
(i.e. sizeof(long) == 4)
Use MAXLOGNAME == 17 for stricter setlogin() size checking. Since
it rounds up to 20, all sizes remains the same
the quality of the hash distribution. This does not fix a problem dealing
with poor distribution when using lots of IP aliases and listening
on the same port on every one of them...some other day perhaps; fixing
that requires significant code changes.
The use of xor was inspired by David S. Miller <davem@jenolan.rutgers.edu>
and getvfsbyname() interfaces. The new interfaces are now hidden from
applications unless _NEW_VFSCONF is defined. The new vfsconf interfaces
don't work yet.
