* btrfs-progs: Add chunk corrupt funtion to btrfs-corrupt-blockQu Wenruo2013-08-09
| | | | | | | | | | | | | | | | Add chunk corrupt function to btrfs-corrupt-block. This funtion can be used to delete or corrupt a given chunk or the whole chunk tree. This funtion is useful to test the coming chunk recover funtion. BTW, since the chunk recover funtion is based on whole partion scanning, so the COW should be disabled and edit leaf without changing generation. Which makes btrfs_commit_transation giving some ignorable warning.

* Add basic RAID[56] supportDavid Woodhouse2013-02-01
| | | | | | | | | | | | | | | | David Woodhouse originally contributed this code, and Chris Mason changed it around to reflect the current design goals for raid56. The original code expected all metadata and data writes to be full stripes. This meant metadata block size == stripe size, and had a few other restrictions. This version allows metadata blocks smaller than the stripe size. It implements both raid5 and raid6, although it does not have code to rebuild from parity if one of the drives is missing or incorrect.

* Btrfsck: add the ability to prune corrupt extent allocation tree blocksChris Mason2012-02-21
| | | | | | | When we discover bad blocks in the extent allocation tree, repair can now discard them and recreate the references from the rest of the trees. Signed-off-by: Chris Mason <chris.mason@oracle.com>
