Modified Files:
src/sys/kern: vfs_vnode.c
src/sys/sys: vnode.h
Log Message:
In vcache_reclaim(), post NOTE_REVOKE immediately after changing the
vnode state to VS_RECLAIMING, before we actually call VOP_RECLAIM(),
which will release the reference on the lower node of a stacked FS
vnode, which is likely to free the upper node's v_klist backing store.
Acquire the vnode interlock when checking for kevent interest now,
because the vp->v_klist pointer is now volatile.
