ima: Rename internal filter rule functions
Rename IMA's internal filter rule functions from security_filter_rule_*() to ima_filter_rule_*(). This avoids polluting the security_* namespace, which is typically reserved for general security subsystem infrastructure. Signed-off-by: Tyler Hicks <tyhicks@linux.microsoft.com> Suggested-by: Casey Schaufler <casey@schaufler-ca.com> [zohar@linux.ibm.com: reword using the term "filter", not "audit"] Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>
