    Subjectwhy is asm-parisc/ioctl.h subtly different from asm-generic/ioctl.h?

    just noticed that parisc's ioctl.h file, rather than simply
    including asm-generic/ioctl.h, has its own copy whose sole
    (meaningful) difference from the generic one is:

    $ diff include/{asm-generic,asm-parisc}/ioctl.h
    ...
    41,42c54,55
    < #define _IOC_WRITE 1U
    < #define _IOC_READ 2U
    ---
    > #define _IOC_WRITE 2U
    > #define _IOC_READ 1U

    so parisc is identical except that it switches the meaning of the
    direction field? is there a reason for this? just curious.
