Add an inode back-pointer to 'struct fscrypt_info', such that inode->i_crypt_info->ci_inode == inode. This will be useful for: 1. Evicting the inodes when a fscrypt key is removed, since we'll track the inodes using a given key by linking their fscrypt_infos together, rather than the inodes directly. This avoids bloating 'struct inode' with a new list_head. 2. Simplifying the per-file key setup, since the inode pointer won't have to be passed around everywhere just in case something goes wrong and it's needed for fscrypt_warn().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
