so consumers handle EINVAL from splice but not ENOSYS?

Precisely. Well, the one I found: grep. But looking at splice(2) man page, consumers probably need to handle it anyway: with early kernels exactly one of the fds had to be a pipe, later both could be, then there's "EINVAL The target filesystem doesn't support splicing"...

emaste accepted this revision.Jul 14 2020, 12:58 AM

Probably worth putting that EINVAL description in a comment by the return.

This revision is now accepted and ready to land.Jul 14 2020, 12:58 AM
