Specifically, do not let vtryrecycle() to recycle a used vnode. It is
possible for a vnode to be vref-ed or vuse-ed lockless after it is held
by vhold_recycle_free(). Then, since vtryrecycle() does not recheck the
hold count, we might end up freeing vused vnode.
Since vget_finish() increments v_usecount after obtaining the vnode
lock, we would observe the hold reference anyway when the parallel
vget() is blocked waiting on the vnode lock.

[ToolChains][FreeBSD] Set default Linker to LLD for FreeBSD (#190596)
When the linker is specified as ld, toolchain applies special handling
by invoking (triple)-ld instead of resolving ld via standard PATH
lookup. This causes GNU ld installed via the system package manager to
take the precedence (since (triple)-ld appears earlier in the search
path), effectively overriding ld.lld.
As a result, we set the default Linker on FreeBSD to ld.lld to indicate
we want to use lld by default.

The extra search for an FEXEC fufh shall be removed, since readdir
is only supposed to be called on a directory opened with FREAD. The
sole exception is NFS, which will call VOP_READDIR with directories that
aren't open at all. fuse already has special code to handle that.
Also remove the fuse_filehandle_get_dir() function, since it's not
used anywhere else.

_loopback entry in `static_routes` ensures a loopback route

However, loopback routes may already be added by the kernel.
Therefore, re-adding them triggers an `EEXIST` error on every boot.

When interface was connected to a link partner with a cable
type limitting maximum supported speed, e.g. SFP+ cable
in 25G port, driver incorrectly saved a supported speed
as the user configured speed. This prevented interface
from using all supported speeds after switching cable to SFP28.
Link was established at 10G as supported by previously used
SFP+ cable. Don't set user requested speed unless actually
configured by an user, to allow automatic selection of highest
available speed. Only when user sets custom config
using advertise_speed sysctl save it and try
to apply after cable is changed.
Also don't save initial supported speeds if FW supports
reporting default PHY config.

When we snl_init_writer() we allocate memory in the struct snl_state in the struct pfctl_handle.
This memory was never released again, leading to a memory leak. We still
had a reference to the memory and would release it on pfctl_close()
(so valgrind did not detect it as a leak), but long-lived users (e.g.
bsnmpd) would eventually run out of memory.
Explicitly reset the snl_state when we're done to prevent this.

This particular change didn't come from upstream. It was added locally
in 7a991ecd1 when attempting to enable the fips provider with 3.0.
Given the fact that we no longer build the fips provider and the fips
provider build process (including sources) is very prescribed to
specific build steps and source versions, there's no reason why we need

mount command, the owner of the file system was "root", and thus

nor does it destroy any of them on exit, except for the control device.
This is harmless if virtual_oss(8) is killed after all audio streams
have been shut down, but if it's killed during I/O, the process hangs
and/or goes into uninterruptible sleep state.
To fix this, have pointers to all cuse(3) devices, and explicitly
destroy them on exit. Also make sure we don't leak memory in

Ergo, arity check is now performed separately via `__assert_sanitize_arity()`, a
unary template whose parameter pack must bind to exactly on argument after
`__VA_ARGS__` is substituted into the call.
Also align NDEBUG with C23 requirements.
