Message-ID: <20090111020352.GA4285@localhost.localdomain> Date: Sun, 11 Jan 2009 11:03:53 +0900 From: Akinobu Mita <akinobu.mita@...il.com> To: Josef Bacik <jbacik@...hat.com> Cc: linux-kernel@...r.kernel.org, akpm@...ux-foundation.org, Theodore Tso <tytso@....edu>, adilger@....com, linux-ext4@...r.kernel.org Subject: [PATCH] ext4: fix unhandled ext4_free_data allocation failure In ext4_mb_free_blocks() ext4_free_data allocation failure is not handled. This error handling cannot be simple error return because ext4_mb_free_blocks() cannot fail. This patch add __GFP_NOFAIL to gfp mask for the allocation.
