[PATCH 3/3] proc: switch over direct seq_read method calls to seq_read_iter

From: Christoph Hellwig
Date: Thu Oct 29 2020 - 06:18:43 EST

Switch over all instances used directly as methods using these sed
expressions:

sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g'

This fixes a problem with the Android bionic test suite using /proc/cpuinfo
and /proc/version for its splice based tests.

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