From c089d490dfbf53bc0893dc9ef57cf3ee6448314d Mon Sep 17 00:00:00 2001 From: Mingming Cao Date: Tue, 16 Oct 2007 18:38:25 -0400 Subject: 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.
