Hi Ingo,

I ran into an OOM problem while testing.  Having heard someone mention
ramdisk troubles, I enabled it and booted with ramdisk_size=16384. Made
an fs (mke2fs /dev/ram0) mounted it and ran Bonnie -s 12 a few times.
Result was terminal OOM.  Everything else seems to work fine, so this
may just be a driver bug(?).  I can't revert my tree just yet to find
out for sure.

Memleak results with line numbers translated to zoned-2.3.28-K2 stock.

buffer.c:1054: 15698 13710 15260 DELTA: 28970
filemap.c:1852: 3430 3448 3921 DELTA: 7369
slab.c:507: 468 173 142 DELTA: 315
