Message-ID: <4828CAC6.3090402@unixsol.org> Date: Tue, 13 May 2008 01:55:02 +0300 From: Georgi Chorbadzhiyski <gf@...xsol.org> To: xfs@....sgi.com, jfs-discussion@...ts.sourceforge.net, cluster-devel@...hat.com CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: Unneeded kernel threads (xfs, jfs, gfs2) Hi guys, I know that not all kernel thread users are converted to start only when needed but the following is little annoying specially when I'm not even using jfs, xfs and gfs2. Look at the ps output from a standard distro 2.6.24.5 kernel after a fresh boot: > PID TTY STAT TIME COMMAND > 2 ? S< 0:00 [kthreadd] > 3 ? S< 0:00 \_ [migration/0] > 4 ?
