tools headers: Update linux/ctype.h with the kernel sources (23cd9543) · Commits · 戴 / test

To pick up the changes in: ("ctype.h: remove duplicate isdigit() helper") Addressing this perf build warning: Warning: Kernel ABI header at 'tools/include/linux/ctype.h' differs from latest version at 'include/linux/ctype.h' diff -u tools/include/linux/ctype.h include/linux/ctype.h And we need to continue using the combination of: inline __isdigit() #define isdigit() __isdigit When the __has_builtin() thing isn't available, as it is a builtin in older systems with it as a builtin but with compilers not hacinv __has_builtin(), rendering the __has_builtin() check useless otherwise.
