perf beauty: Introduce scrape script for the 'statx' syscall 'mask' argument

2024-03-21T16:54:40Z

It was using the first variation on producing a string representation for a binary flag, one that used the system's stat.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/statx_mask.sh static const char *statx_mask[] = { [ilog2(0x00000001) + 1] = "TYPE", [ilog2(0x00000002) + 1] = "MODE", [ilog2(0x00000004) + 1] = "NLINK", [ilog2(0x00000008) + 1] = "UID", [ilog2(0x00000010) + 1] = "GID", [ilog2(0x00000020) + 1] = "ATIME", [ilog2(0x00000040) + 1] = "MTIME", [ilog2(0x00000080) + 1] = "CTIME", [ilog2(0x00000100) + 1] = "INO", [ilog2(0x00000200) + 1] = "SIZE", [ilog2(0x00000400) + 1] = "BLOCKS", [ilog2(0x00000800) + 1] = "BTIME", [ilog2(0x00001000) + 1] = "MNT_ID", [ilog2(0x00002000) + 1] = "DIOALIGN", [ilog2(0x00004000) + 1] = "MNT_ID_UNIQUE", }; $ Now we need a copy of uapi/linux/stat.h from tools/include/ in the scrape only directory tools/perf/trace/beauty/include.
