Using CR_BEST_AVAIL_LEN only make sense for regular files, as for non-regular files we never normalize the allocation request length i.e. goal len is same as original length (ac_g_ex.fe_len == ac_o_ex.fe_len). Hence there is no scope of trimming the goal length to make it satisfy original request len. Thus this patch avoids using CR_BEST_AVAIL_LEN criteria for non-regular files request.

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 Restructured Text 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.
