* update mkfs.btrfs for the new space balancing codeZheng Yan2008-09-26
| | | | | | | The new space balancing code needs a subvol to store the temporary inode for data extent relocation. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Full back reference supportZheng Yan2008-09-23
| | | | | | | | This patch makes the back reference system to explicit record the location of parent node for all types of extents. The location of parent node is placed into the offset field of backref key. Every time a tree block is balanced, the back references for the affected lower level extents are updated.

* btrfs-convert: Iterate correctly using libext2fs functionsRadoslaw Szkodzinski2008-07-30
| | | | | | This patch corrects open-coded inode_map iteration, which happens to be illegal in new libext2fs due to inode_map being private, causing warning, which becomes a compile error.

| | | | | | | Many options were not mentioned in the usage message, fix that and cleaning up the brackets Signed-Off-By: Ahmed Kamal <email.ahmedkamal@googlemail.com>
* Fix: btrfsctl arguments handlingAhmed2008-07-30
| | | | | | btrfsctl -A in the current -unstable branch, does not result in the error message designated for it, namely "-A requires an arg\n"

| | | | This patch updates btrfs-convert for the new dir index format.
* btrfs-progs: add orphan support to print-treeJosef Bacik2008-07-30
| | | | | This adds orphan support to print-tree so when debug_tree hits an orphan item it will print out "orphan item" under it so you know what it is

* Add sync and transaction ioctl defsChris Mason2008-06-10
| | | | | | | | | btrfsctl -c forces a single FS sync The transaction ioctls are unsafe for general use because they can lead to deadlocks if the application is not very careful. But, ceph is experimenting with btrfs as a backing store, and these ioctls are required for testing.

* Fix uninitialized variables, and use -O so gcc starts checking for themChris Mason2008-05-01
| | | | | | | | Gcc only sends warnings for uninitialized variables when you compile with -O, and there were a couple of bugs sprinkled in the code. The biggest was the alloc_start variable for mkfs, which can cause strange things to happen. (thanks to Gabor Micsko for helping to find this)

* Fix btrfs-convert's large file support.Zhu2008-04-28
| | | | | | This patch add ext2_inode.i_size_high into account when calculating regular file's size in btrfs-convert, which makes it deal with large files bigger than 4GB properly.
* Add btrfs-vol command to balance, add and (eventually) remove devicesChris Mason2008-04-28
|
* Add mkfs.btrfs -A offset to control allocation start on devicesChris Mason2008-04-25
| | | | | | This is a utility option for the resizer, it makes sure to allocate at offset bytes in the disk or higher. It ensures the resizer will have something to move when testing it.
* Speed improvement and bug fixes for ext3 converterYan Zheng2008-04-24
| | | | | | | | This patch improves converter's allocator and fixes a bug in data relocation function. The new allocator caches free blocks as Btrfs's default allocator. In testing here, the user CPU time reduced to half of the original when checksum and small file packing was disabled. This patch also enlarges the size of block groups created by the converter.
* Fix balance_level to free the middle block if there is room in the left oneChris Mason2008-04-24
| | | | | | balance level starts by trying to empty the middle block, and then pushes from the right to the middle. This might empty the right block and leave a small number of pointers in the middle.

* Update the Ext3 converterChris Mason2008-04-22
| | | | | | | | | | | The main changes in this patch are adding chunk handing and data relocation ability. In the last step of conversion, the converter relocates data in system chunk and move chunk tree into system chunk. In the rollback process, the converter remove chunk tree from system chunk and copy data back. Regards YZ ---

* Add chunk uuids and update multi-device back referencesChris Mason2008-04-15
| | | | | | | | | | | | | | | | | | Block headers now store the chunk tree uuid Chunk items records the device uuid for each stripes Device extent items record better back refs to the chunk tree Block groups record better back refs to the chunk tree The chunk tree format has also changed. The objectid of BTRFS_CHUNK_ITEM_KEY used to be the logical offset of the chunk. Now it is a chunk tree id, with the logical offset being stored in the offset field of the key. This allows a single chunk tree to record multiple logical address spaces, upping the number of bytes indexed by a chunk tree from 2^64 to 2^128.
