To pick the changes in these csets:
a2fa114d34142d8b ("compat: remove some compat entry points")
bd6a4f8fc6490d4d ("mm: wire up syscall process_mrelease")
91db84c71a31d39c ("exit/bdflush: Remove the deprecated bdflush system call")
That add support for this new syscall in tools such as 'perf trace'.
For instance, this is now possible:
# perf trace -v -e process_mrelease
event qualifier tracepoint filter: (common_pid != 19351 && common_pid != 9112) && (id == 448)
^C#
That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.
$ grep process_mrelease tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
448 common process_mrelease sys_process_mrelease
$
This addresses these perf build warnings:
