      Description

      Once the fallocate() functionality in patch https://review.whamcloud.com/9275 "LU-3606 fallocate: Implement fallocate preallocate operation" is landed, it would be useful to have "lfs migrate" and "lfs mirror extend" call fallocate() to pre-allocate the output file on the OST in order to get more optimal block allocation.
