This reverts commit e7d193073a223663612301c659e53795b991ca89 which is
commit 6a2d30d3c5 upstream.
The dummy_st_ops/dummy_sleepable_reject_null test requires commit 980ca8ceea
("bpf: check bpf_dummy_struct_ops program params for test runs"), which in turn
depends on "Support PTR_MAYBE_NULL for struct_ops arguments" series (see link
below), neither are backported to stable 6.6.
