Ouch. High-order memory allocations anyone?
My preferred approach would be to allocate a slab cache for jffs2
erase blocks. Then we either need a (much smaller) array of pointers
to the slab objects or maintain them as linked lists. But then again,
it wouldn't be the first ugly hack in jffs2. Go right ahead if you
really want to!
