2721  rc = smack_netlabel - Set the secattr on a socket*@sk: the socket*@labeled: socket label scheme* Convert the outbound smack value (smk_out) to a* secattr and attach it to the socket.* Returns 0 on success or an error code
2722  If rc != 0 Then printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers

2735  Return 0
Caller
NameDescribe
smack_inode_notifysecctxThere used to be a smack_release_secctx hook* that did nothing back when hooks were in a vector.* Now that there's a list such a hook adds cost.
