tools headers UAPI: Sync files changed by new set_mempolicy_home_node syscall
To pick the changes in these csets: 21b084fdf2a49ca1 ("mm/mempolicy: wire up syscall set_mempolicy_home_node") That add support for this new syscall in tools such as 'perf trace'. For instance, this is now possible: [root@five ~]# perf trace -e set_mempolicy_home_node ^C[root@five ~]# [root@five ~]# perf trace -v -e set_mempolicy_home_node Using CPUID AuthenticAMD-25-21-0 event qualifier tracepoint filter: (common_pid != 253729 && common_pid != 3585) && (id == 450) mmap size 528384B ^C[root@five ~] [root@five ~]# perf trace -v -e set* --max-events 5 Using CPUID AuthenticAMD-25-21-0 event qualifier tracepoint filter: (common_pid != 253734 && common_pid != 3585) && (id == 38 || id == 54 || id == 105 || id == 106 || id == 109 || id == 112 || id == 113 || id == 114 || id == 116 || id == 117 || id == 119 || id == 122 || id == 123 || id == 141 || id == 160 || id == 164 || id == 170 || id == 171 || id == 188 || id == 205 || id == 218 || id == 238 || id == 273 || id == 308 || id == 450) mmap size 528384B 0.000 ( 0.008 ms): bash/253735 setpgid(pid: 253735 (bash), pgid: 253735 (bash)) = 0 6849.011 ( 0.008 ms): bash/16046 setpgid(pid: 253736 (bash), pgid: 253736 (bash)) = 0 6849.080 ( 0.005 ms): bash/253736 setpgid(pid: 253736 (bash), pgid: 253736 (bash)) = 0 7437.718 ( 0.009 ms): gnome-shell/253737 set_robust_list(head: 0x7f34b527e920, len: 24) = 0 13445.986 ( 0.010 ms): bash/16046 setpgid(pid: 253738 (bash), pgid: 253738 (bash)) = 0 [root@five ~]# That is the filter expression attached to the raw_syscalls:sys_{enter,exit} tracepoints. $ find tools/perf/arch/ -name "syscall*tbl" | xargs grep -w set_mempolicy_home_node tools/perf/arch/mips/entry/syscalls/syscall_n64.tbl:450 common set_mempolicy_home_node sys_set_mempolicy_home_node tools/perf/arch/powerpc/entry/syscalls/syscall.tbl:450 nospu set_mempolicy_home_node sys_set_mempolicy_home_node tools/perf/arch/s390/entry/syscalls/syscall.tbl:450 common set_mempolicy_home_node sys_set_mempolicy_home_node sys_set_mempolicy_home_node tools/perf/arch/x86/entry/syscalls/syscall_64.tbl:450 common set_mempolicy_home_node sys_set_mempolicy_home_node $ $ grep -w set_mempolicy_home_node /tmp/build/perf/arch/x86/include/generated/asm/syscalls_64.c [450] = "set_mempolicy_home_node", $ This addresses these perf build warnings: Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/unistd.h' differs from latest version at 'include/uapi/asm-generic/unistd.h' diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl' diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl Warning: Kernel ABI header at 'tools/perf/arch/powerpc/entry/syscalls/syscall.tbl' differs from latest version at 'arch/powerpc/kernel/syscalls/syscall.tbl' diff -u tools/perf/arch/powerpc/entry/syscalls/syscall.tbl arch/powerpc/kernel/syscalls/syscall.tbl Warning: Kernel ABI header at 'tools/perf/arch/s390/entry/syscalls/syscall.tbl' differs from latest version at 'arch/s390/kernel/syscalls/syscall.tbl' diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl Warning: Kernel ABI header at 'tools/perf/arch/mips/entry/syscalls/syscall_n64.tbl' differs from latest version at 'arch/mips/kernel/syscalls/syscall_n64.tbl' diff -u tools/perf/arch/mips/entry/syscalls/syscall_n64.tbl arch/mips/kernel/syscalls/syscall_n64.tbl Cc: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
