Okay, Points taken, Here is the updated patch to get rid of slab
management and jbd_kmalloc from jbd totally. This patch is intend to
replace the patch in mm tree, Andrew, could you pick up this one
instead?
Thanks,
Mingming
jbd/jbd2: JBD memory allocation cleanups
From: Christoph Lameter <clameter@xxxxxxx>
JBD: Replace slab allocations with page cache allocations
JBD allocate memory for committed_data and frozen_data from slab. However
JBD should not pass slab pages down to the block layer. Use page allocator pages instead. This will also prepare JBD for the large blocksize patchset.
Also this patch cleans up jbd_kmalloc and replace it with kmalloc directly
