Greg, I hope that your linux kernel release scripts are implemented in a way that understands that PATCHLEVEL= and SUBLEVEL= numbers in top-level linux Makefile are encoded as 8-bit numbers for LINUX_VERSION_CODE and KERNEL_VERSION() macros, and must stay in range 0...255. These 8-bit limits are hardcoded in both kernel source and userspace ABI. After 4.9.255 and 4.4.255, your scripts should be incrementing a number in EXTRAVERSION= in top-level linux Makefile. -- Jari Ruusu 4096R/8132F189 12D6 4C3A DCDA 0AA4 27BD ACDF F073 3C80 8132 F189
