of the missing functionality from procfs(4) and new functionality for
monitoring and debugging specific processes. procstat(1) operates in
the following modes:
-b Display binary information for the process.
-c Display command line arguments for the process.
-f Display file descriptor information for the process.
-k Display the stacks of kernel threads in the process.
-s Display security credential information for the process.
-t Display thread information for the process.
-v Display virtual memory mappings for the process.
Further revision and modes are expected.

Until the code is cleaned up, just add -fno-strict-aliasing to the

current tty as returned from ttyname(3) so it can try to avoid writing to
the current tty if possible. Previously, it did this by trimming off any
leading directory (effectively performing a basename(3) on the path
returned from ttyname(3)). However, this chopped off too much of the path
for ttys who have directories in their name such as pts(4). Instead, just
strip off the leading /dev/ from the path returned by ttyname(3). This
fixes write(1) when using pts(4).

kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.
kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.
All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.

At this moment, makewhatis determines the end of the .SH NAME section
as where it finds .SH again, but there is none here, is it "terminated"

support for wide characters.
If the sizeof (wchar_t) times max_length would yield a value beyond
representation in a size_t, exit with a usage error up front, rather than
strange errors down the line from trying to malloc (well, realloc) with a size
of 0.
This is perhaps not the optimal behaviour - a clamp may be more appropriate as
we clamp the value of max_length now anyway, but this is at least better than
segfaulting or worse. On systems which are friendly to malloc with a value of 0
the results could end up being strange corruption of the output.
since "local" includes also synthetic file systems (e.g. /dev, /proc)
and loopback mounts.
This version uses lsvfs to identify file system types that are local
and additionally not synthetik, loopback mounts, or read-only. This
has been suggested by Craig Rodrigues half a year ago. The patch that
has been committed is based on his suggestion, but slightly modified.
The comments in locate.rc have been updated to reflect the change and
o include zfs and xfs in the example file system parameter that can
be used to override the default outlined above.

inspect all local file systems, not only ufs and ext2fs. A number
of local file systems has been added over time, and at least zfs
has the potential to become a popular choice. Without this change
a ZFS root file system causes the script to ignore all file-systems
and leads to an empty locate db. (An alternative is to add all the
relevant file systems individually, which means that at least zfs,
xfs, ntfs, ntfs-3g, msdosfs should be added, probably more).
