Hello,
In preparation for adding inline encryption support to fscrypt, this
patchset adds 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.
This means using

f2fs inode numbers are stable across filesystem resizing, and f2fs inode
and file logical block numbers are always 32-bit. So f2fs can always
support IV_INO_LBLK_64 encryption policies. Wire up the needed
fscrypt_operations to declare support.

Inline encryption hardware compliant with the UFS v2.1 standard or with
the upcoming version of the eMMC standard has the following properties:
(1) Per I/O request, the encryption key is specified by a previously
loaded keyslot. There might be only a small number of

Skip the O_DIRECT tests on f2fs when the test_dummy_encryption mount
option is given, for the same reason as given for ext4 in
commit 9b154b26e4a1 ("common/rc: ext4 doesn't support O_DIRECT with
encryption").

Why don't we mount debugfs first?
Thanks,

Yes.
