From 5bf3258fd2acd8515450ab8efcd97c9d3b69f7f9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 20 Dec 2013 05:16:41 -0800 Subject: fs: make posix_acl_chmod more useful Rename the current posix_acl_chmod to __posix_acl_chmod and add a fully featured ACL chmod helper that uses the ->set_acl inode operation.
