Vishal Goel 2e962e2fec SMACK: Add new lock for adding entry in smack master list ... "smk_set_access()" function adds a new rule entry in subject label specific list(rule_list) and in global rule list(smack_rule_list) both. Mutex lock (rule_lock) is used to avoid simultaneous updates. But this lock is subject label specific lock. If 2 processes tries to add different rules(i.e with different subject labels) simultaneously, then both the processes can take the "rule_lock" respectively. So it will cause a problem while adding entries in master rule list. Now a new mutex lock(smack_master_list_lock) has been taken to add entry in smack_rule_list to avoid simultaneous updates of different rules.
