1# name	meta	args...
2#
3# Where meta contains a string of variants to generate.
4# Upper-case implies _{acquire,release,relaxed} variants.
5# Valid meta values are:
6# * B/b	- bool: returns bool
7# * v	- void: returns void
8# * I/i	- int: returns base type
9# * R	- return: returns base type (has _return variants)
10# * F/f	- fetch: returns base type (has fetch_ variants)
11# * l	- load: returns base type (has _acquire order variant)
12# * s	- store: returns void (has _release order variant)
13#
14# Where args contains list of type[:name], where type is:
15# * cv	- const pointer to atomic base type (atomic_t/atomic64_t/atomic_long_t)
16# * v	- pointer to atomic base type (atomic_t/atomic64_t/atomic_long_t)
17# * i	- base type (int/s64/long)
18# * p	- pointer to base type (int/s64/long)
