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.
