When gfs2 releases the glock of an inode, it must invalidate all
information cached for that inode, including the page cache and acls. Use
the new security_inode_invalidate_secctx hook to also invalidate security
labels in that case. These items will be reread from disk when needed
after reacquiring the glock.
