Subject: random: wire up fops->splice_read_iter()
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=refs%2Fheads%2Frandom-splice;p=linux-2.6-block.git

random: wire up fops->splice_read_iter()

Now that random/urandom is using read_iter, we can wire it up to using
the generic splice read handler.

Fixes: 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops")
