Actually, I don't see any clear-cut policy on the matter (all HACKING
says is that "Typedefs are used to eliminate the redundant 'struct'
keyword", but does not say how aggressively they must be used). In
fact, it looks like most of qemu.git prefers the more compact
representation, while your patch goes to the less-common one:
$ git grep 'typedef struct .* {' | wc
1370 5549 71105
$ git grep 'typedef struct .*;' | wc
624 2515 41449
However, one thing that your style has going for it, that was not
possible with the compact version, is to use:
typedef struct intList intList;
struct intList {
union {
int64_t value;
uint64_t padding;
};
- struct intList *next;
+ intList *next;
};
that is, because your typedef is separate, you have the option of being
able to drop the use of 'struct' from within the actual intList struct.
Again, if we want that, it would be better to do that as a separate commit.
