Rename ext4_insert_delayed_block() to ext4_insert_delayed_blocks(), pass length parameter to make it insert multiple delalloc blocks at a time. For non-bigalloc case, just reserve len blocks and insert delalloc extent. For bigalloc case, we can ensure that the clusters in the middle of a extent must be unallocated, we only need to check whether the start and end clusters are delayed/allocated. We should subtract the space for the start and/or end block(s) if they are allocated.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
