The space is accounted by corresponding fields in jffs2_eraseblock
structure: free_size, wasted_size, used_size.
Jffs2 always writes to c->sector_size - jeb->free_size.
The corresponding place in jffs2_flush_wbuf, where the parameters a
adjusted is wbuf.c:506.
But.. Argh! Look at line 488: if (pad && !jffs2_dataflash(c))
Why !jffs2_dataflash(c)??? I bet this is the bug.
