What tree is that against? Because in mainline your #5 sure as hell
won't apply...
There uio.h has
enum iter_type {
/* iter types */
ITER_IOVEC,
ITER_KVEC,
ITER_BVEC,
ITER_PIPE,
ITER_XARRAY,
ITER_DISCARD,
};
and your series assumes
enum iter_type {
/* iter types */
ITER_IOVEC = 4,
ITER_KVEC = 8,
ITER_BVEC = 16,
ITER_PIPE = 32,
ITER_DISCARD = 64,
};
What had that been tested with?
