Wait, but how will you then find the needed struct jffs2_eraseblock
object by its physical offset on flash ? Use Hash / lists ? Bad idea
(slow). Use array of pointers to each object ? It will be rather large,
and I cannot take easy the fact that we will use distinct pointers for
objects which are mostly physically contiguous in RAM (they are laying
contiguously in slabs). This probably will neglect the pluses of
colouring, which, BTW, we may also organize using my way...
