From f2d6c2708bd84ca953fa6b6ca5717e79eb0140c7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Jan 2021 21:46:31 +0100 Subject: kernfs: wire up ->splice_read and ->splice_write Wire up the splice_read and splice_write methods to the default helpers using ->read_iter and ->write_iter now that those are implemented for kernfs. This restores support to use splice and sendfile on kernfs files.
