Modified Files:
src/sys/kern: vfs_vnode.c
Log Message:
Take the vnode lock before the vnode is marked VI_CHANGING and fed
to vclean(). Prevents a deadlock with two null mounts on the same
physical mount where one thread tries to vclean() a layer node and
another thread tries to vget() a layer node pointing to the same
physical node.
Fixes PR kern/50375 layerfs (nullfs) locking problem leading to livelock
