[PATCH 08/11] seq_file: switch over direct seq_read method calls to seq_read_iter

From: Christoph Hellwig
Date: Wed Jun 24 2020 - 12:30:28 EST

Next message: Masahiro Yamada: "Re: [PATCH 4/4] ARM: dts: uniphier: change support card to simple-mfd from simple-bus"
Previous message: Christoph Hellwig: "[PATCH 11/11] fs: don't allow splice read/write without explicit ops"
In reply to: Christoph Hellwig: "[PATCH 11/11] fs: don't allow splice read/write without explicit ops"
Next in thread: Christoph Hellwig: "[PATCH 02/11] fs: factor out a set_fmode_can_read_write helper"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

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

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