When more than one thread enters ufsdirhash_create() for the same
directory and the inode dirhash is instantiated, but the dirhash' hash
is not, all of them lock the dirhash shared and then try to upgrade.
Since there are several threads owning the lock shared, upgrade fails
and the same attempt is repeated, ad infinitum.
To break the lockstep, lock the dirhash in exclusive mode after the
failed try-upgrade.

This variable should be pure MI except possibly for reading it in MD
dump routines. Its initialization was pure MD in 4.4BSD, but FreeBSD
changed this in r36441 in 1998. There were many imperfections in
r36441. This commit fixes only a small one, to simplify fixing the
others 1 arch at a time. (r47678 added support for
special/early/multiple message buffer initialization which I want in
a more general form, but this was too fragile to use because hacking
on the msgbufp global corrupted it, and was only used for 5 hours in
-current...)
Our dc(1) has never correctly calculated remainders with fractional inputs.
Both bmod and bdivmod seem to have copy/pasted code from bdiv, which results
in the remainder having the wrong output scale.

Currently each call to telldir() requires a malloc and adds an entry to a
linked list which must be traversed on future telldir(), seekdir(),
closedir(), and readdir() calls. Applications that call telldir() for every
directory entry incur O(n^2) behavior in readdir() and O(n) in telldir() and
closedir().
This optimization eliminates the malloc() and linked list in most cases by
packing the relevant information into a single long. On 64-bit architectures
msdosfs, NFS, tmpfs, UFS, and ZFS can all use the packed representation. On
32-bit architectures msdosfs, NFS, and UFS can use the packed
representation, but ZFS and tmpfs can only use it for about the first 128
files per directory. Memory savings is about 50 bytes per telldir(3) call.
Speedup for telldir()-heavy directory traversals is about 20-30x for one
million files per directory.

matching failure.
According to the Open Group documentation for fwscanf:
"Upon successful completion, these functions shall return the number of
successfully matched and assigned input items; this number can be zero in
the event of an early matching failure."
Without this change, fwscanf would return EOF in the case of an early
matching failure, instead of the proper return value of 0.
This change aligns fwscanf(3) with the implementation in fscanf(3).

This change was made to allow zstd(1) to be a dropin replacement for gzip(1) and
friends, allowing easy integration, in particular with newsyslog(8). At the
price of having a zstd(1) command which by default behaves differently than what
upstream default, confusing users.
newsyslog(8) has been adapted to now be more flexible in what it accepts as
compression program, so we can switch back zstd(1) to its default behaviour
Reported by: many
have a semantic different than the traditional gzip(1)
This is done to allow to use zstd(1) as a compression tool without
having to patch it to change its default behavior.
I did a complete buildworld and test... with the program disconnected
from the tree. Revert the change for now.
(this keeps the change to .arclint which is still correct)

Summary:
Some architectures (powerpc Book-E) have a vm_paddr_t larger than intptr_t.
Casting from the intptr_t to vm_paddr_t causes sign extension, leading to a
potentially invalid address.
This was seen when running X on a PowerPC P1022 machine, which mapped the
backing framebuffer at 0xc1800000. When mmap()d by X, this yielded an invalid
address of 0xffffffffc1800000, or, as the hardware would see it, 0xfc1800000.
