[PATCH 22/26] locking/atomic: scripts: simplify raw_atomic_long*() definitions

Mark Rutland
2023-05-22T12:28:50Z

Currently, atomic-long is split into two sections, one defining the
raw_atomic_long_*() ops for CONFIG_64BIT, and one defining the raw
atomic_long_*() ops for !CONFIG_64BIT.

With many lines elided, this looks like:

| #ifdef CONFIG_64BIT
| ...
| static __always_inline bool
| raw_atomic_long_try_cmpxchg(atomic_long_t *v, long *old, long new)
| {
| return raw_atomic64_try_cmpxchg(v, (s64 *)old, new);
| }
| ...
| #else /* CONFIG_64BIT */
| ...
| static __always_inline bool
| raw_atomic_long_try_cmpxchg(atomic_long_t *v, long *old, long new)
| {
| return raw_atomic_try_cmpxchg(v, (int *)old, new);
| }
| ...
| #endif

The two definitions are spread far apart in the file, and duplicate the
prototype, making it hard to have a legible set of kerneldoc comments.

Make this simpler by defining the C prototype once, and writing the two
definitions inline. For example, the above becomes:

| static __always_inline bool
| raw_atomic_long_try_cmpxchg(atomic_long_t *v, long *old, long new)
| {
| #ifdef CONFIG_64BIT
| return raw_atomic64_try_cmpxchg(v, (s64 *)old, new);
| #else
| return raw_atomic_try_cmpxchg(v, (int *)old, new);
| #endif
| }

As we now always have a single copy of the C prototype wrapping all the
potential definitions, we now have an obvious single location for kerneldoc
comments. As a bonus, both the script and the generated file are
somewhat shorter.

There should be no functional change as a result of this patch.
