Andreas Grünbacher reports that on the two filesystems that support
iomap directio, it's possible for splice() to return -EAGAIN (instead of
a short splice) if the pipe being written to has less space available in
its pipe buffers than the length supplied by the calling process.
This is a regression test to check for correct operation. Kernel
needs commit 3253d9d09337 ("splice: only read in as much information
as there is pipe buffer space") to pass.
