mips: use __kernel_{uid,gid}32_t in uapi/asm/stat.h

2022-06-02T15:38:15Z

Commit 8c1a381a4fbb ("mips: add asm/stat.h to UAPI compile-test coverage") converted as follows: uid_t --> __kernel_uid_t gid_t --> __kernel_gid_t The bit width of __kernel_{uid,gid}_t is 16 or 32-bits depending on architectures. MIPS uses 32-bits for them as in include/uapi/asm-generic/posix_types.h, so the previous conversion is probably fine, but let's stick to the arch-independent conversion just in case. The safe replacements across all architectures are: uid_t --> __kernel_uid32_t gid_t --> __kernel_gid32_t as defined in include/linux/types.h. A similar issue was reported for the android binder.

termbits: Convert octal defines to hex

2022-05-05T20:43:58Z

Many archs have termbits.h as octal numbers. It makes hard for humans to parse the magnitude of large numbers correctly and to compare with hex ones of the same define. Convert octal values to hex. First step is an automated conversion with: for i in $(git ls-files | grep 'termbits\.h'); do awk --non-decimal-data '/^#define\s+[A-Z][A-Z0-9]*\s+0[0-9]/ { l=int(((length($3) - 1) * 3 + 3) / 4); repl = sprintf("0x%0" l "x", $3); print gensub(/[^[:blank:]]+/, repl, 3); next} {print}' $i > $i~; mv $i~ $i; done On top of that, some manual processing on alignment and number of zeros. In addition, small tweaks to formatting of a few comments on the same lines.
