tools headers UAPI: Sync s390 syscall table file changed by new futex_waitv syscall
To pick the changes in these csets: 6c122360 ("s390: wire up sys_futex_waitv system call") That add support for this new syscall in tools such as 'perf trace'. For instance, this is now possible (adapted from the x86_64 test output): # perf trace -e futex_waitv ^C# # perf trace -v -e futex_waitv event qualifier tracepoint filter: (common_pid != 807333 && common_pid != 3564) && (id == 449) ^C# # perf trace -v -e futex* --max-events 10 event qualifier tracepoint filter: (common_pid != 812168 && common_pid != 3564) && (id == 238 || id == 449) ?
