>From 3695fbda6225d2436e4af67a4bce6984df0891be Mon Sep 17 00:00:00 2001 From: Nathan Lynch <[email protected]> Date: Mon, 9 Mar 2009 22:36:40 -0500 Subject: [PATCH] ratelimit files_deny_checkpointing output
Any common distribution's boot sequence causes thousands of "<something> performed an action that cannot be checkpointed" messages. Kernels are known to produce other messages of interest at times, so ratelimit the output of files_deny_checkpointing.
