Subject: selinux: simply inode label states to INVALID and INITIALIZED
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4b57d6bcd94034e2eb168bdec2474e3b2b848e44;p=linux-beck.git

selinux: simply inode label states to INVALID and INITIALIZED

There really is no need for LABEL_MISSING as we really only care if
the inode's label is INVALID or INITIALIZED.  Also adjust the
revalidate code to reload the label whenever the label is not
INITIALIZED so we are less sensitive to label state in the future.
