a new jail parameter node with the following parameters:
allow.mount.devfs:
allow mounting the devfs filesystem inside a jail
allow.mount.nullfs:
allow mounting the nullfs filesystem inside a jail
Both parameters are disabled by default (equals the behavior before
devfs and nullfs in jails). Administrators have to explicitly allow
mounting devfs and nullfs for each jail. The value "-1" of the
devfs_ruleset parameter is removed in favor of the new allow setting.

"panic in 8.3-PRERELEASE" on Feb. 22, 2012. This panic was caused
by use of a mix of tsleep() and msleep() calls on the same event
in the new NFS server DRC code. It did "mtx_unlock(); tsleep();"
in two places, which kib@ noted introduced a slight risk that the
wakeup() would occur before the tsleep(), resulting in a 10sec
delay before waking up. This patch fixes the problem by replacing
"mtx_unlock(); tsleep();" with mtx_sleep(..PDROP..). It also
changes a nfsmsleep() call to mtx_sleep() so that the code uses
mtx_sleep() consistently within the file.

I'm not sure _why_ the ic is NULL here, but I've seen it occasionally do
this after I've been tinkering with things for a while. It ends up
crashing in a call to ath_chan_set() via the net80211 scan code and scan
task.

Also remove infinite loop in interrupt handler and limit number of

under high network load.

Since 'hpt27xx_driver_name' is a constant string symbol (coming from the
proprietary hpt27xx_lib.o file), there is no security problem.
Because this driver is provided by the vendor, and applying changes
requires re-certification and other bureaucratic exercises, just disable
the warning for now.
