There are a number of patches committed to upstream in the last couple of days
that might fix your problem.  See:

	https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/

and look for:

	pipe: Fix iteration end check in fuse_dev_splice_write()
	pipe: fix incorrect caching of pipe state over pipe_wait()
	pipe: Fix missing mask update after pipe_wait()
	pipe: Remove assertion from pipe_poll()
