ima: allocating iint improvements
With IMA-appraisal's removal of the iint mutex and taking the i_mutex instead, allocating the iint becomes a lot simplier, as we don't need to be concerned with two processes racing to allocate the iint. This patch cleans up and improves performance for allocating the iint. - removed redundant double i_mutex locking - combined iint allocation with tree search Changelog v2: - removed the rwlock/read_lock changes from this patch Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Signed-off-by: Mimi Zohar <zohar@us.ibm.com>
