- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.

and advice in the development of this patch.
SCHED_OTHER happens to be 0, so this assignment to "int *" succeeds,
and becomes a no-op.
Fix by dereferencing "policy" to do the assignment, thus filling the
return buffer with 0.
Fixes first part of PR#31184. addrsort() was not exposed to the rest of
libc as it turns out not to be usable for getaddrinfo(), so a different
sorter will be implemented for that.
policies and enforcing them in programs.
Man-page written with much help and tips from David Maxwell, Hubert
Feyrer, and Thomas Klausner.
This bumps libutil minor to 7.
XXX: Need default policy to go in /etc/passwd.conf, and integration
into local/yp/PAM password changing code.
PR/10206.
The cause of this is that in the re-entrant case we block all signals until
we timeout. Convert this to use pollts and then grab the pending signals
and sigsuspend them.
XXX: We should really convert this to use kqueue, like FreeBSD did.
