From 1209bbdff2f6bbffa6eb5823033bbd7b8799a5e2 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Thu, 2 Oct 2014 20:13:35 +0400 Subject: [PATCH] CIFS: Fix readpages retrying on reconnects If we got a reconnect error from async readv we re-add pages back to page_list and continue loop. That is wrong because these pages have been already added to the pagecache but page_list has pages that have not been added to the pagecache yet. This ends up with a general protection fault in put_pages after readpages. Fix it by not retrying the read of these pages and falling back to readpage instead.
