| * | Btrfs: fix regression in scrub path resolving | Jan Schmidt | 2012-03-27 |
| | | | | | | | | | | | | | | In commit 4692cf58 we introduced new backref walking code for btrfs. This assumes we're searching live roots, which requires a transaction context. While scrubbing, however, we must not join a transaction because this could deadlock with the commit path. Additionally, what scrub really wants to do is resolving a logical address in the commit root it's currently checking. This patch adds support for logical to path resolving on commit roots and makes scrub use that. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net> | ||
| * | Btrfs: added btrfs_find_all_roots() | Jan Schmidt | 2012-01-04 |
| | | | | | | | | | | | | | This function gets a byte number (a data extent), collects all the leafs pointing to it and walks up the trees to find all fs roots pointing to those leafs. It also returns the list of all leafs pointing to that extent. It does proper locking for the involved trees, can be used on busy file systems and honors delayed refs.

| * | btrfs: added helper functions to iterate backrefs | Jan Schmidt | 2011-09-29 |
| These helper functions iterate back references and call a function for each backref. There is also a function to resolve an inode to a path in the file system. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net> | |||
