fs: btrfs: Fix wrong comparison in logical to physical mapping
The comparison
logical > item->logical + item->length
in btrfs_map_logical_to_physical is wrong and should be instead
logical >= item->logical + item->length
For example, if
item->logical = 4096
item->length = 4096
and we are looking for logical = 8192, it is not part of item (item is
[4096, 8191]). But the comparison is false and we think we have found
the correct item, although we should be searing in the right subtree.
This fixes some bugs I encountered.
