Implement kernel labeling of the MLS (multilevel security) field of security contexts for files which have no existing MLS field. This is to enable upgrades of a system from non-MLS to MLS without performing a full filesystem relabel including all of the mountpoints, which would be quite painful for users. With this patch, with MLS enabled, if a file has no MLS field, the kernel internally adds an MLS field to the in-core inode (but not to the on-disk file). This MLS field added is the default for the superblock, allowing per-mountpoint control over the values via fixed policy or mount options. This patch has been tested by enabling MLS without relabeling its filesystem, and seems to be working correctly.
