4Subject: [PATCH] uatomic: Specify complete types for atomic function calls
5
6This was unearthed by clang compiler where it complained about parameter
7mismatch, gcc doesnt notice this
8
9urcu/uatomic/generic.h:190:10: error: address argument to atomic builtin
10must be a pointer to integer or pointer ('void *' invalid)
11 return __sync_add_and_fetch_4(addr, val);
12
13Fixed all instances thusly
