[PATCH v2 0/3] btrfs-progs: Fix logical-resolve

[Marcos Paulo de Souza <marcos@mpdesouza.com>]

From: Marcos Paulo de Souza <mpdesouza@suse.com>

New issues were found while testing the v1, and new problems with the current
implementation too. Now focusing on a generic way of detecting where to do the
file lookup based in the logical offset of the file.

Now there is a test to avoid this problem from appearing again in the future.

Please let me know if this can be improved even further.

Changes from v1:
* Patches 2 and 3 added
* Test created (David)
* Discard changed on btrfs_list_path_for_root and changing find_mount_root
  instead

First version:
