Add the appropriate calls into fscrypt for various actions, including link, rename, setattr, and the open codepaths. Disable fallocate for encrypted inodes -- hopefully, just for now. If we have an encrypted inode, then the client will need to re-encrypt the contents of the new object. Disable copy offload to or from encrypted inodes. Set i_blkbits to crypto block size for encrypted inodes -- some of the underlying infrastructure for fscrypt relies on i_blkbits being aligned to crypto blocksize. Report STATX_ATTR_ENCRYPTED on encrypted inodes.

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.
