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.

dependencies. In particular, it may need this while syncing filesystem
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.

Some notable changes:
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

shouldn't belong. This means we didn't properly unlock the TTY before

This caching allows for completely lock-free allocation/deallocation in the
steady state, at the expense of likely increased memory use and
fragmentation.
Reduce the default number of arenas to 2*ncpus, since thread-specific
caching typically reduces arena contention.
Modify size class spacing to include ranges of 2^n-spaced, quantum-spaced,
cacheline-spaced, and subpage-spaced size classes. The advantages are:
fewer size classes, reduced false cacheline sharing, and reduced internal
fragmentation for allocations that are slightly over 512, 1024, etc.
Increase RUN_MAX_SMALL, in order to limit fragmentation for the
subpage-spaced size classes.
Add a size-->bin lookup table for small sizes to simplify translating sizes
to size classes. Include a hard-coded constant table that is used unless
custom size class spacing is specified at run time.
Add the ability to disable tiny size classes at compile time via
MALLOC_TINY.
