    [PATCH] s390: fadvise hint values. · 068e1b94

    Add special case for the POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE hint
    values for s390-64.  The user space values in the s390-64 glibc headers for
    these two defines have always been 6 and 7 instead of 4 and 5.  All 64 bit
    applications therefore use the "wrong" values.  To get these applications
    working without recompiling the kernel needs to accept the "wrong" values.
    Since the values for s390-31 are 4 and 5 the compat wrapper for fadvise64
    and fadvise64_64 need to rewrite the values for 31 bit system calls.
