Eric Biggers b30501efe9 ANDROID: fscrypt: fall back to filesystem-layer crypto when needed
When the filesystem is mounted with '-o inlinecrypt', make fscrypt fall
back to filesystem-layer crypto when inline crypto won't work, e.g. due
to the hardware not supporting the encryption algorithm.

When blk-crypto-fallback is disabled, this fixes '-o inlinecrypt' to not
break any fscrypt policies that would otherwise work.

This is needed for VtsKernelEncryptionTest to pass on some devices.

Bug: 137270441
Bug: 151100202
Test: 'atest vts_kernel_encryption_test' on Pixel 4 with the
      inline crypto patches backported, and also on Cuttlefish.

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.
