If upperrootvp is doomed by a concurrent unmount, unionfs_nodeget()
may return without a reference or lock on it. unionfs_domount() must
prevent the vnode from being recycled for use by a different file until
it is finished with the vnode, namely once vfs_register_upper_from_vp()
fails. Accomplish this by holding the reference returned by namei()
a bit longer.

If either the lower or upper vnode is found to be doomed after
locking it, the newly-created unionfs node won't be associated
with it and its lock will be dropped. In that case, clear the
uppervp and lowervp locals as necessary to avoid further use
of the vnode in unionfs_nodeget(). If the upper vnode is doomed
but the lower vnode remains valid, additionally reset the unionfs
node's v_vnlock field to point to the lower vnode lock.

In many cases this avoids an extra lookup, since the callers always have
pm at hand. We can also eliminate several assertions, mostly for pm !=
NULL. The class methods are an internal interface, and the callers
already handle such a scenario. No functional change intended.

Provide the log type names in their entirely, rather than relying on the

Although this block has remained in __PMC_EVENTS(), there is no handling
of UCP in libpmc/libpmc.c, so it is not possible to select one of these
events. It should therefore be impossible to trigger the code removed
from ucp_start_pmc(). Note that the GQ_SNOOP_MSF MSR exists only for
Nehalem and Westmere architectures, and the related events do not exist
for later generations.
The Uncore support in hwpmc has severely atrophied in general. We have
uncore event definitions in pmu-events, but the kernel support was
written against Intel Performance Measurement Architecture version 2,
and is disabled for processor generations later than Westmere. Nehalem
and Westmere lack uncore event definitions in pmu-events. I'd be
surprised if Uncore support is usable on any machine in its current
state.

If the i-node number (d_fileno) for a file on the server did

This is no longer correct, given that ino_t is now 64bits.
This patch fixes this by sending the full 64bits of d_fileno
