Objects are created either by d_alloc_name()+d_add() (in binderfs_ctl_create()) or by simple_start_creating()+d_instantiate(). Removals are by simple_recurisive_removal(). Switch d_add()/d_instantiate() to d_make_persistent() + dput(). Voila - kill_litter_super() is not needed anymore. Fold dput()+unlocking the parent into simple_done_creating(), while we are at it. NOTE: return value of binderfs_create_file() is borrowed; it may get stored in proc->binderfs_entry. See binder_release()... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
