[PATCH] Manage jbd allocations from its own slabs
JBD currently allocates commit and frozen buffers from slabs. With CONFIG_SLAB_DEBUG, its possible for an allocation to cross the page boundary causing IO problems. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200127 So, instead of allocating these from regular slabs - manage allocation from its own slabs and disable slab debug for these slabs.
