From 9f46080c41d5f3f7c00b4e169ba4b0b2865258bf Mon Sep 17 00:00:00 2001 From: Matt Helsley Date: Mon, 7 Nov 2005 00:59:16 -0800 Subject: [PATCH] Process Events Connector This patch adds a connector that reports fork, exec, id change, and exit events for all processes to userspace. It replaces the fork_advisor patch that ELSA is currently using. Applications that may find these events useful include accounting/auditing (e.g. ELSA), system activity monitoring (e.g. top), security, and resource management (e.g. CKRM).

Some have extra blank lines (not allowed immed. after the function name) or need blank lines (after all parameters). Function summary must be only one line. Colon (":") in a function description does weird things (causes kernel-doc to think that it's a new section head sadly).
