"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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
