Message-ID: <Pine.LNX.4.63.0609071300330.1700@pcgl.dsa-ac.de> Date: Thu, 7 Sep 2006 13:10:59 +0200 (CEST) From: Guennadi Liakhovetski <gl@...-ac.de> To: sct@...hat.com, akpm@...l.org, adilger@...sterfs.com Cc: linux-kernel@...r.kernel.org Subject: [2.6.18-rc6] ext3 memory leak Hi all, this looks like a serious problem to be fixed before 2.6.18 final and backported to 2.6.17.*. Or a case of me misunderstanding something, in which case, please, let me know. I've reported before in thread "[2.6.17.4] slabinfo.buffer_head increases" a memory leak in ext3. Today I verified it is still present in 2.6.18-rc6. A short description: as long as write accesses are made on an ext3 filesystem /proc/slabinfo buffer_head increases unboundedly. This behaviour is not observed with another journalling filesystems (e.g., reiserfs), or if ext3 is mounted as ext2. As it seems serious enough to me I'm sending it to ext3 maintainers.
