Hello,
This series adds an xfstest which tests that the encryption for
IV_INO_LBLK_64 encryption policies is being done correctly.
IV_INO_LBLK_64 is a new fscrypt policy flag which modifies the
encryption to be optimized for inline encryption hardware compliant with
the UFS v2.1 standard or the upcoming version of the eMMC standard. For
more information, see the kernel patchset:
https://lore.kernel.org/linux-fscrypt/20191024215438.138489-1-ebiggers@xxxxxxxxxx/T/#u
The kernel patches have been merged into mainline and will be in v5.5.
In addition to the latest kernel, to run on ext4 this test also needs a
version of e2fsprogs built from the master branch, in order to get
support for formatting the filesystem with '-O stable_inodes'.
As usual, the test will skip itself if the prerequisites aren't met.
No real changes since v1; just rebased onto the latest xfstests master
branch and updated the cover letter.
