Subject: [PATCH] mm/filemap.c: Remove unused argument from shrink_readahead_size_eio()
Date:   Wed, 11 Mar 2020 00:51:33 +0530
Message-Id: <1583868093-24342-1-git-send-email-jrdr.linux@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The first argument of shrink_readahead_size_eio() is not used. Hence
removed from function definition and from all the callers.
