To get the changes in: e346b38 ("mm/mremap: add MREMAP_DONTUNMAP to mremap()") Add that to 'perf trace's mremap 'flags' decoder. This silences this perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/mman.h' differs from latest version at 'include/uapi/linux/mman.h' diff -u tools/include/uapi/linux/mman.h include/uapi/linux/mman.h Cc: Adrian Hunter <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Brian Geffon <[email protected]> Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
