[Yaffs] is this a bug or my mis-use

when i migrate yaffs to my system,i found that i may open a file that
are soft-deled and inserted into dev->gc_cleanup_list[].
function yaffs_bg_gc() run periodly ,this file will be removed in this
while i'm willing to use this file.
and i modified the logic as that:call yaffs_generic_obj_del() after
soft-del and the scituation before is gone. is this ok?
