Christoph, Have you been able to replicate this problem since rebooting your machine. I've never seen anything quite like your report before. If you do, a couple of questions. Which slab allocator are you using? Are you using SLAB or SLUB? (grep for CONFIG_SLAB or CONFIG_SLUB in your .config file). If you are using SLUB, it would be useful to compile slubinfo.c (found in /usr/src/linux/Documentation/vm/slabinfo.c) and send us the output "slabinfo -a ext4_allocation_context" and "slabinfo -r ext4_allocation_context". Also, you might try "slabinfo -s" and see if that shrinks the slabs for you. If this works, why it wasn't doing this automatically is beyond me. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
