Okay
Similar behaviour on ppc64 too.
I modified the script a bit to
probe kernel.statement("aio_complete@fs/aio.c:1012")
{
printf ("%s \n", $$locals)
exit()
}
Now the output shows
ctx=0xffff8802231d4e00 info=? ring=? event=? flags=0x213 tail=0x6f ret=0x0
mod_name=0x840fa4 descriptor=?
This seems to support what you are suggesting that it could be a optimization issue.
