This is done in order to have a common code base for implementing "post read" processing across filesystems. Changelog: RFC -> V1: 1. Add a new patch to implement S_VERITY/IS_VERITY(). 2. Split code that replaces filesystem specific routines with generic IS_ENCRYPTED() and IS_VERITY() calls into separate patches.
