Need to consider what's expected when migrating from a former non-FM UBI system to an FM enabled system, in the case where all PEBs where consumed (reserved) in the former system. > How much PEB should be reserved? 2 x sizeof(fastmap)? Since FM does not use EBA's atomic LEB change when writing the new fastmap, but instead implements its own FM "leb change" internally - then reserving 2x is needed if we'd like to avoid reusing the same fastmap PEB.
