Not that I know of. It'll be limited by max open fds but I don't

There is no need to have a nlmsghdr pointer to another temporary buffer.
Instead use a full struct nlmsghdr.

The return type of ffs() is 'int' on all architectures except cris and

The problem I'm seeing is that the following line generates a warning
on cris and hexagon because of the mismatch between format '%u' and
return type of ffs().

event is disabled but a dummy software event is not
disabled.
