From e2a07812e93d4a51b1b1a6f15145a1634948db47 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Tue, 23 Mar 2010 09:52:55 +1100 Subject: xfs: add blockdev name to kthreads This allows to see in `ps` and similar tools which kthreads are allotted to which block device/filesystem, similar to what jbd2 does. As the process name is a fixed 16-char array, no extra space is needed in tasks. PID TTY STAT TIME COMMAND 2 ? S 0:00 [kthreadd] 197 ? S 0:00 \_ [jbd2/sda2-8] 198 ? S 0:00 \_ [ext4-dio-unwrit] 204 ?
