Stefan Berger 3253804773 security: allow finer granularity in permitting copy-up of security xattrs
Copying up xattrs is solely based on the security xattr name. For finer
granularity add a dentry parameter to the security_inode_copy_up_xattr
hook definition, allowing decisions to be based on the xattr content as
well.
