Now that we have the code to support encryption for subpage-sized blocks, this commit removes the conditional check in filesystem mount code. The commit also changes the support statement in Documentation/filesystems/fscrypt.rst to reflect the fact that encryption on filesystems with blocksize less than page size now works. [EB: Tested with 'gce-xfstests -c ext4/encrypt_1k -g auto', using the new "encrypt_1k" config I created. All tests pass except for those that already fail or are excluded with the encrypt or 1k configs, and 2 tests that try to create 1023-byte symlinks which fails since encrypted symlinks are limited to blocksize-3 bytes. Also ran the dedicated encryption tests using 'kvm-xfstests -c ext4/1k -g encrypt'; all pass, including the on-disk ciphertext verification tests.] Signed-off-by: Chandan Rajendra <chandan@linux.ibm.com> Signed-off-by: Eric Biggers <ebiggers@google.com> Link: https://lore.kernel.org/r/20191023033312.361355-3-ebiggers@kernel.org Signed-off-by: Theodore Ts'o <tytso@mit.edu>
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.
