Module Name:    src
Committed By:   sommerfeld
Date:           Thu Mar 25 00:20:35 UTC 1999

Modified Files:
        src/sys/sys: lock.h
        src/sys/kern: kern_lock.c vfs_vnops.c
        src/sys/uvm: uvm_vnode.c
Log Message:
Prevent deadlock cited in PR4629 from crashing the system.  (copyout
and system call now just return EFAULT).  A complete fix will
presumably have to wait for UBC and/or for vnode locking protocols to
be revamped to allow use of shared locks.
