Subject: Re: [PATCH] Security/sysfs: Enable security xattrs to be set on
 sysfs files, directories, and symlinks.

I just read over Casey's comments again and I'm pretty sure we have a
big misunderstanding here. From his initial response it seems that he
thinks that I am exposing the secids to userspace as the way for setting
the labels on files. That isn't true. We are still using the full string
based labels for the userspace interface what the secid is used for is
to allow the kernel to keep track of changes until the sysfs_dirent is
destroyed.
