* When mending lost pages, also see if they fit into length specified in object index header

* Instead of exact object id:s in the object lookup tables, use a hash of span index and object id.
|
|
|
|
|
Eg. object id xor:ed with bit-reversed span index.
|
|
|
|
|
This should decrease number of actual pages that needs to be visited when looking thru the obj lut.

|
* Logical number of each block. When moving stuff in a garbage collected page, the free
|
|
|
|
|
page is assigned the same number as the garbage collected. Thus, object index pages do not have to
|
|
|
|
|
be rewritten.
|
|
|
|

|
|
* Steal one page, use as a bit parity page. When starting an fs modification operation, write one bit
|
|
|
|
|
as zero. When ending, write another bit as zero. On mount, if number of zeroes in page is uneven, a
|
|
|
|
|
check is automatically run.
