Don't abuse si_errno and deliver all of the perf data in _perf member of siginfo_t. Note: The data field in the perf data structures in a u64 to allow a pointer to be encoded without needed to implement a 32bit and 64bit version of the same structure. There already exists a 32bit and 64bit versions siginfo_t, and the 32bit version can not include a 64bit member as it only has 32bit alignment. So unsigned long is used in siginfo_t instead of a u64 as unsigned long can encode a pointer on all architectures linux supports. v1: https://lkml.kernel.org/r/[email protected] v2: https://lkml.kernel.org/r/[email protected] v3: https://lkml.kernel.org/r/[email protected] Link: https://lkml.kernel.org/r/[email protected] Reviewed-by: Marco Elver <[email protected]> Signed-off-by: "Eric W.
