| 2024-09-30 | tools include UAPI: Sync linux/fcntl.h copy with the kernel sources | Arnaldo Carvalho de Melo | 1 | -0/+5 | |
| Picking the changes from: 4356d575ef0f39a3 ("fhandle: expose u64 mount id to name_to_handle_at(2)") b4fef22c2fb97fa2 ("uapi: explain how per-syscall AT_* flags should be allocated") 820a185896b77814 ("fcntl: add F_CREATED_QUERY") It just moves AT_REMOVEDIR around, and adds a bunch more AT_ for renameat2() and name_to_handle_at(). We need to improve this situation, as not all AT_ defines are applicable to all fs flags... This adds support for those new AT_ defines, addressing this build warning: diff -u tools/perf/trace/beauty/include/uapi/sound/asound.h include/uapi/sound/asound.h Reviewed-by: Aleksa Sarai <cyphar@cyphar.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Christian Brauner <brauner@kernel.org> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Tejun Heo <tj@kernel.org> Link: https://lore.kernel.org/lkml/ZvrIKL3cREoRHIQd@x1 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> | |||||
| 2024-03-21 | perf beauty: Introduce scrape script for various fs syscalls 'flags' arguments | Arnaldo Carvalho de Melo | 1 | -0/+21 | |
| It was using the first variation on producing a string representation for a binary flag, one that used the system's fcntl.h and preprocessor tricks that had to be updated everytime a new flag was introduced. Use the more recent scrape script + strarray + strarray__scnprintf_flags() combo. $ tools/perf/trace/beauty/fs_at_flags.sh static const char *fs_at_flags[] = { [ilog2(0x100) + 1] = "SYMLINK_NOFOLLOW", [ilog2(0x200) + 1] = "REMOVEDIR", [ilog2(0x400) + 1] = "SYMLINK_FOLLOW", [ilog2(0x800) + 1] = "NO_AUTOMOUNT", [ilog2(0x1000) + 1] = "EMPTY_PATH", [ilog2(0x0000) + 1] = "STATX_SYNC_AS_STAT", [ilog2(0x2000) + 1] = "STATX_FORCE_SYNC", [ilog2(0x4000) + 1] = "STATX_DONT_SYNC", [ilog2(0x8000) + 1] = "RECURSIVE", [ilog2(0x80000000) + 1] = "GETATTR_NOSEC", }; $ Now we need a copy of uapi/linux/fcntl.h from tools/include/ in the scrape only directory tools/perf/trace/beauty/include and will use that fs_at_flags array for other fs syscalls.
