3.16.54-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit 34be4dbf87fc3e474a842305394534216d428f5d upstream. isofs uses a 'char' variable to load the number of years since 1900 for an inode timestamp. On architectures that use a signed char type by default, this results in an invalid date for anything beyond 2027. This changes the function argument to a 'u8' array, which is defined the same way on all architectures, and unambiguously lets us use years until 2155. This should be backported to all kernels that might still be in use by that date.
