Subject: [f2fs-dev] [PATCH v13 09/12] fs: introduce SB_INLINECRYPT
Date: Thu, 14 May 2020 00:37:24 +0000 [thread overview]
Message-ID: <20200514003727.69001-10-satyat@google.com> (raw)
In-Reply-To: <20200514003727.69001-1-satyat@google.com>
Introduce SB_INLINECRYPT, which is set by filesystems that wish to use
blk-crypto for file content en/decryption. This flag maps to the
'-o inlinecrypt' mount option which multiple filesystems will implement,
and code in fs/crypto/ needs to be able to check for this mount option
in a filesystem-independent way.
