perf beauty: Introduce scrape script for various fs syscalls 'flags' arguments
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.
