This patchset unified a large part of chunk allocator (free device
extent search) between kernel and btrfs-progs.
And reuses kernel function structures like btrfs_finish_chunk_alloc()
and btrfs_alloc_dev_extent().
Before the unification:
Kernel | Btrfs-progs
btrfs_alloc_chunk() | btrfs_alloc_chunk()
|- __btrfs_alloc_chunk() | |- Do all the work
|
btrfs_create_pending_block_groups() |
|- btrfs_insert_item() |
|- btrfs_finish_chunk_alloc() |
|- btrfs_alloc_dev_extent() |
After the unification:
Kernel | Btrfs-progs
btrfs_alloc_chunk() | btrfs_alloc_chunk()
|- __btrfs_alloc_chunk() | |- __btrfs_alloc_chunk()
| |- btrfs_finish_chunk_alloc()
btrfs_create_pending_block_groups() | |- btrfs_alloc_dev_extent()
|- btrfs_insert_item() |
|- btrfs_finish_chunk_alloc() |
And the similiar functions are share the same code base, with minor
member/functions change.
Changelog:
v2:
Make error handler in patch 7 better.
New patches to unify more functions used in btrfs_alloc_chunk()
v3:
Use standard library function qsort() to replace the kernel sort(),
suggested by David.
Qu Wenruo (9):
btrfs-progs: Refactor parameter of BTRFS_MAX_DEVS() from root to
fs_info
btrfs-progs: Merge btrfs_alloc_data_chunk into btrfs_alloc_chunk
btrfs-progs: Make btrfs_alloc_chunk to handle block group creation
btrfs-progs: Introduce btrfs_raid_array and related infrastructures
btrfs-progs: volumes: Allow find_free_dev_extent() to return maximum
hole size
btrfs-progs: volumes: Unify free dev extent search behavior between
kernel and btrfs-progs.
btrfs-progs: Move chunk stripe size calcution function to volumes.h
btrfs-progs: Use btrfs_device->fs_info to replace
btrfs_device->dev_root
btrfs-progs: Refactor btrfs_alloc_chunk to mimic kernel structure and
behavior
