locking/atomics: Switch to generated atomic-long As a step towards ensuring the atomic* APIs are consistent, let's switch to wrappers generated by gen-atomic-long.h, using the same table that gen-atomic-fallbacks.h uses to fill in gaps in the atomic_* and atomic64_* APIs. These are checked in rather than generated with Kbuild, since: * This allows inspection of the atomics with git grep and ctags on a pristine tree, which Linus strongly prefers being able to do. * The fallbacks are not affected by machine details or configuration options, so it is not necessary to regenerate them to take these into account. * These are included by files required *very* early in the build process (e.g. for generating bounds.h), and we'd rather not complicate the top-level Kbuild file with dependencies. Other than *_INIT() and *_cond_read_acquire(), all API functions are implemented as static inline C functions, ensuring consistent type promotion and/or truncation without requiring explicit casts to be applied to parameters or return values. Since we typedef atomic_long_t to either atomic_t or atomic64_t, we know these types are equivalent, and don't require explicit casts between them. However, as the try_cmpxchg*() functions take a pointer for the 'old' parameter, which may be an int or s64, an explicit cast is generated for this. There should be no functional change as a result of this patch (i.e. existing code should not be affected). However, this introduces a number of functions into the atomic_long_* API, bringing it into line with the atomic_* and atomic64_* APIs.

locking/atomics: Switch to generated atomic-long As a step towards ensuring the atomic* APIs are consistent, let's switch to wrappers generated by gen-atomic-long.h, using the same table that gen-atomic-fallbacks.h uses to fill in gaps in the atomic_* and atomic64_* APIs. These are checked in rather than generated with Kbuild, since: * This allows inspection of the atomics with git grep and ctags on a pristine tree, which Linus strongly prefers being able to do. * The fallbacks are not affected by machine details or configuration options, so it is not necessary to regenerate them to take these into account. * These are included by files required *very* early in the build process (e.g. for generating bounds.h), and we'd rather not complicate the top-level Kbuild file with dependencies. Other than *_INIT() and *_cond_read_acquire(), all API functions are implemented as static inline C functions, ensuring consistent type promotion and/or truncation without requiring explicit casts to be applied to parameters or return values. Since we typedef atomic_long_t to either atomic_t or atomic64_t, we know these types are equivalent, and don't require explicit casts between them. However, as the try_cmpxchg*() functions take a pointer for the 'old' parameter, which may be an int or s64, an explicit cast is generated for this. There should be no functional change as a result of this patch (i.e. existing code should not be affected). However, this introduces a number of functions into the atomic_long_* API, bringing it into line with the atomic_* and atomic64_* APIs.

locking/atomics: Switch to generated atomic-long As a step towards ensuring the atomic* APIs are consistent, let's switch to wrappers generated by gen-atomic-long.h, using the same table that gen-atomic-fallbacks.h uses to fill in gaps in the atomic_* and atomic64_* APIs. These are checked in rather than generated with Kbuild, since: * This allows inspection of the atomics with git grep and ctags on a pristine tree, which Linus strongly prefers being able to do. * The fallbacks are not affected by machine details or configuration options, so it is not necessary to regenerate them to take these into account. * These are included by files required *very* early in the build process (e.g. for generating bounds.h), and we'd rather not complicate the top-level Kbuild file with dependencies. Other than *_INIT() and *_cond_read_acquire(), all API functions are implemented as static inline C functions, ensuring consistent type promotion and/or truncation without requiring explicit casts to be applied to parameters or return values. Since we typedef atomic_long_t to either atomic_t or atomic64_t, we know these types are equivalent, and don't require explicit casts between them. However, as the try_cmpxchg*() functions take a pointer for the 'old' parameter, which may be an int or s64, an explicit cast is generated for this.

locking/atomics: Switch to generated atomic-long As a step towards ensuring the atomic* APIs are consistent, let's switch to wrappers generated by gen-atomic-long.h, using the same table that gen-atomic-fallbacks.h uses to fill in gaps in the atomic_* and atomic64_* APIs. These are checked in rather than generated with Kbuild, since: * This allows inspection of the atomics with git grep and ctags on a pristine tree, which Linus strongly prefers being able to do. * The fallbacks are not affected by machine details or configuration options, so it is not necessary to regenerate them to take these into account. * These are included by files required *very* early in the build process (e.g. for generating bounds.h), and we'd rather not complicate the top-level Kbuild file with dependencies. Other than *_INIT() and *_cond_read_acquire(), all API functions are implemented as static inline C functions, ensuring consistent type promotion and/or truncation without requiring explicit casts to be applied to parameters or return values. Since we typedef atomic_long_t to either atomic_t or atomic64_t, we know these types are equivalent, and don't require explicit casts between them. However, as the try_cmpxchg*() functions take a pointer for the 'old' parameter, which may be an int or s64, an explicit cast is generated for this. There should be no functional change as a result of this patch (i.e. existing code should not be affected). However, this introduces a number of functions into the atomic_long_* API, bringing it into line with the atomic_* and atomic64_* APIs.

locking/atomics: Switch to generated atomic-long As a step towards ensuring the atomic* APIs are consistent, let's switch to wrappers generated by gen-atomic-long.h, using the same table that gen-atomic-fallbacks.h uses to fill in gaps in the atomic_* and atomic64_* APIs. These are checked in rather than generated with Kbuild, since: * This allows inspection of the atomics with git grep and ctags on a pristine tree, which Linus strongly prefers being able to do. * The fallbacks are not affected by machine details or configuration options, so it is not necessary to regenerate them to take these into account. * These are included by files required *very* early in the build process (e.g. for generating bounds.h), and we'd rather not complicate the top-level Kbuild file with dependencies. Other than *_INIT() and *_cond_read_acquire(), all API functions are implemented as static inline C functions, ensuring consistent type promotion and/or truncation without requiring explicit casts to be applied to parameters or return values. Since we typedef atomic_long_t to either atomic_t or atomic64_t, we know these types are equivalent, and don't require explicit casts between them. However, as the try_cmpxchg*() functions take a pointer for the 'old' parameter, which may be an int or s64, an explicit cast is generated for this. There should be no functional change as a result of this patch (i.e. existing code should not be affected). However, this introduces a number of functions into the atomic_long_* API, bringing it into line with the atomic_* and atomic64_* APIs.
