+ * @lock: the spin lock for this block group
* @block: the free block (group relative) to allocate
- * @bh: the bufferhead containts the block group bitmap

*
* We think we can allocate this block in this bitmap. Try to set the bit.
* If that succeeds then check that nobody has allocated and then freed the

- * @size: the target new reservation window size
+ * @my_rsv: the reservation window
*
- * @group_first_block: the first block we consider to start
+ * @sb: the super block

* @last_block:
*
* failed: we failed to find a reservation window in this group

- * @rsv: the reservation
+ * @my_rsv: the reservation window

* @grp_goal: The goal (group-relative). It is where the search for a

* @group: given allocation block group
* @bitmap_bh: bufferhead holds the block bitmap
* @grp_goal: given target block within the group
- * @count: target number of blocks to allocate
* @my_rsv: reservation window

* This is the main function used to allocate a new block and its reservation
