    Subject[PATCH -V5 05/24] vfs: Add IS_RICHACL() test for richacl support
    Date
    From: Andreas Gruenbacher <agruen@suse.de>

    Introduce a new MS_RICHACL super-block flag and a new IS_RICHACL() test
    which file systems like nfs can use. IS_ACL() is true if IS_POSIXACL()
    or IS_RICHACL() is true.
