Subject: [PATCH] s390/uapi: fix struct statfs64 definition
With b8668fd0a7e1b59f "s390/uapi: change struct statfs[64] member types
to unsigned values" the size of a couple of struct statfs64 member got
incorrectly changed from 64 to 32 bit for 32 bit builds.
Fix this by changing the type of couple of struct statfs64 members from
unsigned long to unsigned long long.
The definition of struct compat_statfs64 was correct however.
