1.7	19-Mar-2019	ryo	add INIT_ONCE(9), FINI_ONCE(9) with changing once_t. Welcome to 8.99.36
1.6	15-Mar-2009	cegger	branches: 1.6.64; ansify function definitions
1.5	09-Oct-2008	pooka	branches: 1.5.2; 1.5.8; Atomic ops are unnecessary here. pointed out by ad
1.4	09-Oct-2008	pooka	Rewrite once to use global locks and atomic ops to get rid of the static simplelock initializer (and simplelock too). The fastpath is still lockless, so doesn't make a difference in terms of performance. Also fixes a hanging bug if the once routine returned an error. It does not retry after an error occurs, as I can't really imagine fruitful semantics for that.
1.3	16-Jan-2006	yamt	branches: 1.3.16; 1.3.70; 1.3.74; 1.3.76; 1.3.80; - tweak RUN_ONCE api to allow init_func returns an error. - physio: handle failure of workqueue_create.
