From: Satya Tangirala Date: Thu, 2 Jul 2020 01:56:04 +0000 (+0000) Subject: fs: introduce SB_INLINECRYPT X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=457e7a135cbf0a0b5ed2717c192c0c57112c3b32;p=linux.git fs: introduce SB_INLINECRYPT 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.
