Subject: audit: include auditd's threads in audit_log_start() wait exception
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f48a942926c58e4b2dfc3f21c58579d5435841ef;p=linux-beck.git

audit: include auditd's threads in audit_log_start() wait exception

Should auditd spawn threads, allow all members of its thread group to
use the audit_backlog_limit reserves to bypass the queue limits too.
