The commit message mentions MSG_SPLICE_PAGES as an internal flag.

It can be passed from userspace. The code anticipates that and checks
preconditions.
Should I add a separate field in the in-kernel msghdr struct for such internal
flags?  That would also avoid putting an internal flag in the same space as
the uapi flags.
