5 * Everybody gets this wrong and has to stick with it for all
6 * eternity. Hopefully, this version gets used by new architectures
7 * so they don't fall into the same traps.
8 *
9 * stat64 is copied from powerpc64, with explicit padding added.
10 * stat is the same structure layout on 64-bit, without the 'long long'
11 * types.
12 *
13 * By convention, 64 bit architectures use the stat interface, while
14 * 32 bit architectures use the stat64 interface. Note that we don't
15 * provide an __old_kernel_stat here, which new architecture should
16 * not have to start with.
