once it is lost, all data is gone.
Option '-B none' can by used to prevent backup. Option '-B path' can be
used to backup metadata to a different file than the default, which is
/var/backups/<prov>.eli.
The 'geli init' command also prints backup file location and gives short
procedure how to restore metadata.
The 'geli setkey' command now warns that even after passphrase change or keys
update there could be version of the master key encrypted with old
keys/passphrase in the backup file.
Add regression tests to verify that new functionality works as expected.
Update other regression tests so they don't create backup files.

1 means that witness is up and running.
0 means that witness is disabled but that it can be established later
again in effective way.
-1 means that witness is disabled permanently
- Fix a bug causing kernel to panic on witness disabling through
witness_watch. lock lists queues were still full of entries and this was
causing throubles with debugging stubs (like witness_thread_exit()).

While merging back my changes from Perforce, it seemed I removed a
locking assertion that still applies to ttydisc_rint_poll(). Restore it,
because it may come in handy.
- Implement IMAXBEL. It turned out the IMAXBEL termios switch was marked
as supported, while it had not been implemented.
- Don't go into the high watermark when in canonical mode, no data has
been canonicalized and the input buffer is full. This caused the
terminal to lock up. This prevented users from pressing
backspace/^U/etc in such cases.
This could easily be simulated by pasting a very big amount of data in
a shell with sh(1) in canonical mode.

because the media was removed, the periph would get its refcount dropped
and ultimately freed before getting unlocked. This created a dangling
pointer that was easy to trip over. This fixes a common source of
crashes with removaable media, but problems remain and will get tracked
down.

- changes in support of the VLAN filter fix to 126850
- removal of a bunch of legacy code that was cruft, if not
possibly harmful.
- removal of POLLING from this driver, with multiqueue and
MSIX it just makes no sense here.
- Fix an LRO bug that I've been working on internally, intermittent
panics under stress, the problem was releasing the RX ring lock
before the LRO flushing.
- Following the above fix I now enable LRO by default
- For performance reasons increase the default number of RX queues
to 4.
- Add AIM - "Adaptive Interrupt Moderation", a fancy way of saying
that the EITR value is dynamically changed based on the size of
packets in the last interrupt interval.
- Much goodness to try, enjoy!!
A couple of months ago I was quite impressed, because when I was writing
code, I discovered that uiomove() would not allow any locks to be held,
while ureadc() did, mainly because ureadc() is implemented using the
same building blocks as uiomove().
Let's see if this triggers any aditional witness warnings on our source
tree.

Previously it may have contained unnecessary (even sensitive) data from
the previous allocation.
As a (good) side effect, scratch memory may be used to store the previous
filter state(s) safely because it is allocated and freed with filter itself.
However, use it carefully because bpf_filter(9) does not have this behavior.

insert new vnode into the mount vnode list. Then, for the SU-enabled
mount, ffs_vfree could create freefile dependency. This dependency can
hang around forever since inode is not marked as IN_MODIFIED and
correspondingly inodeblock may be not marked as dirty.
After ffs_vget() fails, retry with FFSV_FORCEINSMQ, mark the inode as
modified, and vput() it immediately. Take care of the dup alloc.

being unmounted. Since during unmount MNTK_NOINSMNTQUE flag is set,
that could sometimes disallow insertion of the vnode into the vnode
mount list, softdep code needs to overwrite the MNTK_NOINSMNTQUE flag.
Create the ffs_vgetf() function that sets the VV_FORCEINSMQ flag for
new vnode and use it consistently from the softdep code instead of
ffs_vget().
Add the retry logic to the softdep_flushfiles() to flush the vnodes
that could be instantiated while flushing softdep dependencies.
