sys/kern : vfs_subr.c
sys/uvm : uvm_aobj.c uvm_device.c uvm_object.c
uvm_vnode.c
Log message:
Sprinkle uvm_obj_destroy() over UVM object recycling code.
For now, only assert that the tree of pages is empty in uvm_obj_destroy().
This will soon be used to free the per-UVM object lock.
While here call uvm_obj_init() when new vnodes are allocated instead of
in uvn_attach(). Because vnodes and there associated UVM object are
currently never freed, it isn't easy to know where/when to garbage
collect the associated lock. So simply check that the reference of a
given object is 0 when uvn_attach().
Tested by many as part of a bigger diff.
