Subject: [RFC PATCH 24/79] fs: add struct inode to nobh_writepage() arguments
Date: Wed, 4 Apr 2018 15:17:59 -0400 [thread overview]
Message-ID: <20180404191831.5378-10-jglisse@redhat.com> (raw)
In-Reply-To: <20180404191831.5378-1-jglisse@redhat.com>
From: Jérôme Glisse <jglisse@redhat.com>
Add struct inode to nobh_writepage(). Note this patch only add arguments
and modify call site conservatily using page->mapping and thus the end
result is as before this patch.
One step toward dropping reliance on page->mapping.
