4818bd986c When getting mount information for all filesystems, mount uses the
getfsstat(2) system call using the MNT_NOWAIT flag to indicate that
it wants to use the statfs information cached in the mount structure.
When the -v (verbose) flag is specified, we need to use the MNT_WAIT
flag to getfsstat(2) so that kernel will call VFS_STATFS to get the
current statfs statistics from each filesystem.

31260bf042 vfs_donmount: in certain cases try r/o mount if r/w mount fails
If the operation is not an update, if neither r/w nor r/o mode is
explicitly requested, if the error code hints at the possibility of the
media being read-only, and if the fallback is allowed, then we can try
to automatically downgrade to the readonly mode.

This is especially useful for auto-mounting of removable media that
sometimes can happen to be write-protected.

The fallback to r/o is not enabled by default.  It can be requested on a
per-mount basis with a new mount option, 'autoro'.  Or it can be
globally allowed by setting vfs.default_autoro.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

1f3aded066 Fix "mount -uw /" when the filesystem type doesn't match.
This basically makes "mount -uw /" work when the filesystem
mounted on / is NFS, but the one configured in fstab(5) is UFS,
which can happen when you forget to modify fstab.

Note that the whole special case ("else if (argv[0][0] == '/'")
is probably not needed anyway.  I'll take a look at removing it
altogether; for now this is a minimally intrusive fix.

b5bbeb2117 Fix "mount -a" for NFS and ZFS filesystems with shared mountpoints
sbin/mount.c
	Check whether an fstab entry has the same fstype as a mounted
	filesystem before declaring it to be mounted. This will allow NFS
	filesystems that share a mountpoint with a local filesystem to be
	automatically mounted at boot.

	This is not such an unusual situation. For example, if somebody uses
	the standard installer with a ZFS root, he'll get a /usr/home
	filesystem, even though he may choose to mount /usr/home over NFS.

   | Re-implement the root mount logic using a recursive approach, whereby each
   |root file system (starting with devfs and a synthesized configuration) can
   |contain directives for mounting another file system as root.
   |------------------------------------------------------------------------

This commit adds a mount.conf(8) man page which documents
the root mount logic.  mount.conf(8) also provides some examples
for the /.mount.conf file, which can be used to change the root mount behavior.

requirement for SMBFS.

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.

Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.
