Now that the fscrypt_master_key lifetime has been reworked to not be subject to the quirks of the keyrings subsystem, blk_crypto_evict_key() no longer gets called after the filesystem has already been unmounted. Therefore, there is no longer any need to hold extra references to the filesystem's request_queue(s). (And these references didn't always do their intended job anyway, as pinning a request_queue doesn't necessarily pin the corresponding blk_crypto_profile.) Stop taking these extra references. Instead, just pass the super_block to fscrypt_destroy_inline_crypt_key(), and use it to get the list of block devices the key needs to be evicted from.

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.
