[lvm-devel] [LVM2 PATCH] (1/5) Separate mirror log allocation from _alloc_parallel_areas()

[Jun'ichi Nomura]

This patch moves the log allocation part from _alloc_parallel_area().
Preparation for the following patches.
No functional change.

  - _alloc_parallel_area() doesn't need to allocate struct alloced_area
    for log_area because it's pre-allocated in struct alloc_handle.

  - consume_pv_area() has been done in the separate loop from
    the loop for struct alloced_area setup.
    However, consume_pv_area() just updates given pv_area and
    pv_areas in areas[] are different each other.
    So it can be done in the same loop with the struct alloced_area setup.

  - ah->total_area_len, area_len, *ix and ah->area_multiple are not
    used/updated in log_area allocation.
    So operation on them can be moved before _alloc_log_area().

Thanks,
