- Split allocation and freeing of the configuration descriptor into a separate
function, so that the configuration descriptor can be made fixed size
to save memory allocations. This applies for both device and host mode.
There is no point in hiding, e.g. pmc.xscale(3) from a developer running
on amd64, when the target arch in question will probably never have
manual pages installed at all.

is accessible. For msdosfs, this means that FAT entries for the file
must be written.
Since we do not track the FAT blocks containing entries for the
current file, just do a sloppy sync of the devvp vnode for the mount,
which buffers, among other things, contain FAT blocks.
Simultaneously, for deupdat():
- optimize by clearing the modified flags before short-circuiting a
return, if the mount is read-only;
- only ignore the rest of the function for denode with DE_MODIFIED
flag clear when the waitfor argument is false. The directory buffer
for the entry might be of delayed write;
- microoptimize by comparing the updated directory entry with the
current block content;
- try to cluster the write, fall back to bawrite() if low on
resources.

insmntque() is called. The standard insmntque destructor resets the
vop vector to deadfs one, and calls vgone() on the vnode. As result,
v_object is kept unchanged, which triggers an assertion in the reclaim
code, on instmntque() failure. Also, in this case, OBJ_TMPFS flag on
the backed vm object is not cleared.
Provide the tmpfs insmntque() destructor which properly clears
OBJ_TMPFS flag and resets v_object.

as "must" for SATL devices, hence indicating that the device is at least
likely to support Pass-Through (16).
This eliminates errors produced by CTL when ATA Pass-Through (16) fails.
Switch ATA probe daerror call to SF_NO_PRINT to avoid errors printing out
for devices which return invalid errors.

The pipe2() function is similar to pipe() but allows setting FD_CLOEXEC and
O_NONBLOCK (on both sides) as part of the function.
If p points to two writable ints, pipe2(p, 0) is equivalent to pipe(p).
If the pointer is not valid, behaviour differs: pipe2() writes into the
array from the kernel like socketpair() does, while pipe() writes into the
array from an architecture-specific assembler wrapper.

The accept4() function, compared to accept(), allows setting the new file
descriptor atomically close-on-exec and explicitly controlling the
non-blocking status on the new socket. (Note that the latter point means
that accept() is not equivalent to any form of accept4().)
The linuxulator's accept4 implementation leaves a race window where the new
file descriptor is not close-on-exec because it calls sys_accept(). This
implementation leaves no such race window (by using falloc() flags). The
linuxulator could be fixed and simplified by using the new code.
Like accept(), accept4() is async-signal-safe, a cancellation point and
permitted in capability mode.
