FUSE might be interesting - fuse_dev_splice_read() and its ilk.
Communications between the kernel and fuse server at least used to
seriously want that, so that would be one place to look for unhappy
userland...

splice-related logics in fs/fuse/dev.c is interesting; another place
like this is kernel/trace/, but I'm less familiar with that one.
