i use it in yaffs2 mode,and run yaffs_bg_gc() as a background thread
has a  lower priority than threads that operate files.in the
yaffs_gc_block(),i locked before yaffs_generic_obj_del() and unlocked
after it finished.
the effect is same as you said using without soft del.but if using
soft del,some yaffs_obj will be reused after soft del and before
recycled. and this may cause some problem that dev->gc_cleanup_list[]
record this obj and deleted it background.
