The parameter desc_size in fsverity_create_info() is useless and it is not referenced anywhere. The greatest meaning of desc_size here is to indecate the size of struct fsverity_descriptor and futher calculate the size of signature. However, the desc->sig_size can do it also and it is indeed, so remove it. Therefore, it is no need to acquire desc_size by fsverity_get_descriptor() in ensure_verity_info(), so remove the parameter desc_ret in fsverity_get_descriptor() too.

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.
