bac19b3c94 [btree_checker] no longer need to check the checksum, since the block validator has already done this. 2013-05-07 15:47:43 +01:00

44d0b1903f [btree] allow visitors to trap node access failures such as checksum error. 2013-05-07 15:22:13 +01:00

8e0271b3bf [btree] When walking a btree use a validator when taking the locks. 
We really can't rely on anything in the block if the checksum is
wrong.

1e14e1cd10 [metadata_checker_t] fix silly allocation bug in the devices_visitor. 2013-05-07 14:29:54 +01:00
Joe Thornber
d113ff6e5a thin restorer is now careful to share the mapping tree for empty devices. 
This saves a lot of metadata space if you're creating lots of empty
devs (4k per dev).  Also makes things faster since we don't have to
allocate.

edf16f59c7 [restorer] Mappings only get inserted when the device is completed. 
This saves looking up the device mapping tree for every insert.

5d0b23beea Some btree visitor tidying.

add a depth field to keep track of the depth from root.
