While dm-default-key no longer requires that the filesystem is also
using inline encryption (i.e. mounted with '-o inlinecrypt'), it does
still rely on the inline crypto hooks like fscrypt_set_bio_crypt_ctx()
being built into the kernel rather than stubbed out, as these are used
to set the bi_skip_dm_default_key flag on bios for encrypted files.
I.e., CONFIG_FS_ENCRYPTION_INLINE_CRYPT=y is still needed.
The proper solution is to fix these hooks to handle DM_DEFAULT_KEY &&
!FS_ENCRYPTION_INLINE_CRYPT, but that would introduce a case that
wouldn't get tested. So for now, to avoid problems just make
dm-default-key depend on FS_ENCRYPTION_INLINE_CRYPT.
Test: make gki_defconfig
echo CONFIG_FS_ENCRYPTION_INLINE_CRYPT=n >> .config
make olddefconfig
grep CONFIG_DM_DEFAULT_KEY .config # was disabled

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.
