In the mean time, until somebody can substantiate that claim... is AIO SMP
safe? I see that aiocb.aio_buf is declared as "volatile", so I would
presume so.
I just want to be sure that, if an aio call runs on one CPU, another CPU
can access *aio_buf and be 100% certain that the data are coherent.
aio_buf = mmap() using MAP_HASSEMAPHORE -- good idea, bad idea, pointless?
TIA,
Eddy
