[PATCH -V1 02/22] vfs: Add IS_RICHACL() test for richacl support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andreas Gruenbacher <agruen@xxxxxxxxxx>

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.
