again. This is useful until locking is further developed and basically
any deadlocks can be solved by killing appropriate processes.
Thanks especially to Tommi Kyntola and Antti Louko for sitting down
with me and discussing resource ownership and locking strategies
in implementing this.
Make sure that if we pull a buffer off of the read queue that it really
is a read request. Lower in this routine we base which queue we
dequeue the request from on its read/write state. Thus if a write
op ever ended up on the read queue, we'd explode (dereference NULL).
workaround for the problem analyzed more deeply in kern/30831. In
short, the problem is keeping the vnode on the mount point vnode
list during reclaim. If reclaim happens to sleep (as is a possibility
with smbfs due to calling vrele() and therefore possibly VOP_INACTIVE),
code going through the entire mountpoint vnode list will hit
half-reclaimed vnodes.
implement volume control in software via audio filter framework.
XXX: audio filter framework doesn't let me pass parameters from the hw
softc to the filter, so the volume variables are globals for now.
using db->seq() and match comparison rather than db->get().
* Deleting multiple keys of the same name appears to already work as-is
with a single db->del() call; I had code to implement this if '-D'
is given but it appears to be unnecessary.
* Cosmetic/KNF tweaks.
for one more that is needed, and commented out partial implementations for
the test of the functions. This should stop the re-defined symbol errors
for now.
examples in the wscons.conf). Now, you have to specify wscons
control device and put variable name and parameter on separate
fields.
NB: changes ARE NOT backward compatible and config file must be
checked (but default config doesn't utilizing setvar).
are based on completely different alphabet, and typesetting with
one of modifiers pressed all the time is just a PITA). See

usage details.
While here, perform the following small cleanups:
- KS_Cmd_Scroll* execution should be explicitly interrupted with 'break'.
- Some 'human' cleanups in ksym extraction algorithm (no func. changes).
- Add a note: implemented ksym translation isn't sufficient for l10n.
Unfortunately it is too difficult to make vfwscanf and this share
the same code like I did with printf, because for string parsing
the code is too different.
