This is a note to let you know that I have just added a patch titled mm: Remove false WARN_ON from pagecache_isize_extended() to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From c8ec5f10cec1c46afe1cc7ca55c024164952d834 Mon Sep 17 00:00:00 2001 From: Jan Kara <jack@suse.cz> Date: Thu, 30 Oct 2014 10:35:00 +1100 Subject: mm: Remove false WARN_ON from pagecache_isize_extended() commit f55fefd1a5a339b1bd08c120b93312d6eb64a9fb upstream. The WARN_ON checking whether i_mutex is held in pagecache_isize_extended() was wrong because some filesystems (e.g. XFS) use different locks for serialization of truncates / writes. So just remove the check.
