For directories with encrypted files/filenames, we need to store a flag indicating this fact. There's no room in other fields, so we'll need to borrow a bit from dir_type. Since it's now a combination of type and flags, we rename it to dir_flags to reflect its new usage. The new flag, FT_ENCRYPTED, indicates a directory containing encrypted data, which is orthogonal to file type; therefore, add the new flag, and make conversion from directory type to file type strip the flag. As the file types almost never change we can afford to use the bits. Actual usage will be guarded behind an incompat bit, this patch only adds the support for later use by fscrypt.

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.
