Subject: [PATCH v8 7/8] f2fs: support direct I/O with fscrypt using blk-crypto
Date: Thu, 21 Jan 2021 23:03:35 +0000 [thread overview]
Message-ID: <20210121230336.1373726-8-satyat@google.com> (raw)
In-Reply-To: <20210121230336.1373726-1-satyat@google.com>
From: Eric Biggers <ebiggers@google.com>
Wire up f2fs with fscrypt direct I/O support. direct I/O with fscrypt is
only supported through blk-crypto (i.e. CONFIG_BLK_INLINE_ENCRYPTION must
have been enabled, the 'inlinecrypt' mount option must have been specified,
and either hardware inline encryption support must be present or
CONFIG_BLK_INLINE_ENCYRPTION_FALLBACK must have been enabled). Further,
direct I/O on encrypted files is only supported when the *length* of the
I/O is aligned to the filesystem block size (which is *not* necessarily the
same as the block device's block size).
