Hosts the 0x221E linux distro kernel. https://git.0xinfinity.dev/distro/kernel.git/atom?h=master 2024-03-21T13:41:27Z 2024-03-21T13:41:27Z Arnaldo Carvalho de Melo 2024-03-11T20:07:33Z urn:sha1:faf7217a397f041f146a4cf6d9f1c9bd99cd5ca4 It is mostly used only to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. The only case where it was being used to build was in tools/perf/trace/beauty/sync_file_range.c, because some older systems doesn't have the SYNC_FILE_RANGE_WRITE_AND_WAIT define, just use the system's linux/fs.h header instead, defining it if not available. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just <linux/fs.h> coming from either 'make install_headers' or from the system /usr/include/ directory.

Now it should be possible to just use: perf trace -e sync_file_range As root and see all sync_file_range syscalls with its args beautified.
