If no CPU list is passed, timerlat in user-space will dispatch
one thread per sysconf(_SC_NPROCESSORS_CONF). However, not all

Currently, rtla timerlat is stopping the session if an user-space
thread cannot set affinity to a CPU, or if a
The osnoise/per_cpu/CPU$/timerlat_fd is create for each possible

Fine, I'll drop that. It's still correct that a filesystem needs to take
care when it frees sb->s_fs_info. See the RCU fun you just encountered.
If, for any reason, `tx_stats_num + rx_stats_num` wraps around, the
protection that struct_size() adds against potential integer overflows
is defeated. Fix this by hardening call to struct_size() with size_add().
