| |
prompted by the earlier post on "volatile"s, is there a reason that most atomic_t typedefs use volatile int's, while the rest don't?
$ grep "typedef.*struct" $(find . -name atomic.h) ./include/asm-v850/atomic.h:typedef struct { int counter; } atomic_t; ./include/asm-mips/atomic.h:typedef struct { volatile int counter; } atomic_t; ./include/asm-mips/atomic.h:typedef struct { volatile long counter; } atomic64_t; ...
etc, etc. just curious.
