Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Eric Biggers:
"This release, we add support for inline encryption via the blk-crypto
framework which was added in 5.8.
Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
the contents of encrypted files will be encrypted/decrypted via
blk-crypto, instead of directly using the crypto API. This model
allows taking advantage of the inline encryption hardware that is
integrated into the UFS or eMMC host controllers on most mobile SoCs.
Note that this is just an alternate implementation; the ciphertext
written to disk stays the same.
(This pull request does *not* include support for direct I/O on
encrypted files, which blk-crypto makes possible, since that part is
still being discussed.)
Besides the above feature update, there are also a few fixes and
cleanups, e.g. strengthening some memory barriers that may be too
weak.
All these patches have been in linux-next with no reported issues.
I've also tested them with the fscrypt xfstests, as usual. It's also
been tested that the inline encryption support works with the support
for Qualcomm and Mediatek inline encryption hardware that will be in
the scsi pull request for 5.9. Also, several SoC vendors are already
using a previous, functionally equivalent version of these patches"
