Arnaldo Carvalho de Melo 6c3c184fc4 tools headers API: Update faccessat2 affected files ... Update the copies of files affected by: c8ffd8bcdd ("vfs: add faccessat2 syscall") To address this perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/fcntl.h' differs from latest version at 'include/uapi/linux/fcntl.h' diff -u tools/include/uapi/linux/fcntl.h include/uapi/linux/fcntl.h 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 Which results in 'perf trace' gaining support for the 'faccessat2' syscall, now one can use: # perf trace -e faccessat2 And have system wide tracing of this syscall. And this also will include it; # perf trace -e faccess* Together with the other variants.
