CVS commit: src



Module Name:    src
Committed By:   pooka
Date:           Wed Dec  1 14:59:39 UTC 2010

Modified Files:
        src/lib/librumpuser: rumpuser_pth.c
        src/sys/rump/include/rump: rumpuser.h
        src/sys/rump/librump/rumpkern: intr.c klock.c locks.c ltsleep.c rump.c
            rump_private.h

Log Message:
Track lwp as the rumpuser mutex owner instead of pthread_t (this
is done in rumpuser for simplicity, since on the kernel side things
we assume we have only one pointer of space).  As a side-effect,
we can no longer know if the current thread is holding on to a
mutex locked without curlwp context (basically all mutexes inited
outside of mutex_init()).  The only thing that called rumpuser_mutex_held()
for a non-kmutex was the giant lock.  So, instead implement recursive
locking for the giant lock in the rump kernel and get rid of the
now-unused recursive pthread mutex in the hypercall interface.
