while looking at the functions in atomic.h i noticed that there seems to be no atomic_exchg_*() in the API, though this is a supported function in most/all supported archiectures, and a useful function. We do have atomic_readandclear() which uses the same underlying CPU instruction. Again, any objection if i add it ? cheers luigi
