JBD: JBD slab allocation cleanups
JBD: Replace slab allocations with page 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. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Mingming Cao <cmm@us.ibm.com>
