* Add a readonly flag open_ctree to force RO opensChris Mason2008-05-05

* 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.
* 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 support for filesystem labels via mkfs.btrfs -LChris Mason2008-04-18

* Use device uuids when scanning devicesChris Mason2008-04-18

* Add raid10 supportChris Mason2008-04-16

* 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.
* Recow all roots at the end of mkfsChris Mason2008-04-04
| | | | | | The mkfs code bootstraps the filesystem on a single device. Once the raid block groups are setup, it needs to recow all of the blocks so that each tree is properly allocated.

* During deletes and truncate, remove many items at once from the treeChris Mason2008-01-29

* Rename the extent_map code to extent_ioChris Mason2008-03-04
| | | | This mirrors the changes in the kernel code.
* Unaligned access fixesDavid Miller2008-02-15
| | | | | | | | | | | | | The first problem is that these SETGET macros lose typing information, and therefore can't see the 'packed' attribute and therefore take unaligned access SIGBUS signals on sparc64 when trying to derefernce the member. The next problem is a similar issue in btrfs_name_hash(). This gets passed things like &key.offset which is a member of a packed structure, losing this packed'ness information btrfs_name_hash() performs a potentially unaligned memory access, again resulting in a SIGBUS.

* Add readonly inode flagYan2008-01-14
| | | | | This patch adds readonly inode flag support. A file with this flag can't be modified, but can be deleted.
* A few update for btrfs-progsYan2008-01-08
| | | | | | | Hello, This patch adds inode flags definition to btrfs-progs and updates extent-tree.c to match the kernel.
* Update find_free_extent for the ext3 conversion toolYan2008-01-04
| | | | | This patch adds customized find_free_extent support to btrfs-progs, the conversion program requires this.

* btrfs-progs support for root block accountingJosef Bacik2007-08-29
| | | | | | This adds support for keeping track of the number of blocks used by root_item's. This makes it so that mkfs lays down the "default" subvol with the correct block accounting in place. Thank you,
