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.

to ignore the unmounting and forces insertion of the vnode into the mount
vnode list.
Change insmntque() to fail when forced unmount is in progress and
VV_FORCEINSMQ is not specified.
Add an assertion to the insmntque(), requiring the vnode to be
exclusively locked for mp-safe filesystems.
Use the VV_FORCEINSMQ for the creation of the syncvnode.

o add support for AR2316 parts (aka Cobra)
o add support for AR2317 parts (aka Spyder)
o add support for AR2417 parts (aka Nala)
o add support for AR2425 parts (aka Swan)
o add support for AR5416 parts operating in legacy and (receive only) 11n
o add support for 900MHz radios from Ubiquiti and Zcomax
(regdomains 0x9, 0x19a, and country code 843 yield proper channel lists)
o add support for 1/2 and 1/4 rate channels in the public safety band
o add api's to get+set SIFS timing
o misc changes for esoteric eeprom configurations and new eeprom formats
o reduce stack usage
o return chip tx power limits in the channel list
o numerous fixes to the Anti Noise Immunity (ANI) algorithm
o handle anomalous noise floor data better
o add 11n OFDM spoofing compatibility hooks
o fix transmit trigger threshold auto-adjust
o add PCIe power management for PCIe parts
o add WiSoC builds

For some reason a return-statement crept into this code, where it
shouldn't belong. This means we didn't properly unlock the TTY before
