This patch fixes an imbalance message as reported by J.R. Okajima. The IMA file counters are incremented in ima_path_check. If the actual open fails, such as ETXTBSY, decrement the counters to prevent unnecessary imbalance messages. Reported-by: J.R. Okajima <hooanon05@yahoo.co.jp> Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
