I liked all these articles....perhaps a suggestion for a new article: klogd and its internal. First it started with me reading this: http://the-hydra.blogspot.com/2009/03/kernel-panic-when-calling-printk-inside.html and the comment was on klogd....but in my 2.6.31-rc9, i was not able to find any klogd kernel when I do a "ps -ef", showing the following list instead: root 2 0 0 10:42 ? 00:00:00 [kthreadd] root 3 2 0 10:42 ? 00:00:00 [migration/0] root 4 2 0 10:42 ? 00:00:00 [ksoftirqd/0] root 5 2 0 10:42 ? 00:00:00 [watchdog/0] root 6 2 0 10:42 ? 00:00:00 [migration/1] root 7 2 0 10:42 ? 00:00:00 [ksoftirqd/1] root 8 2 0 10:42 ? 00:00:00 [watchdog/1] root 9 2 0 10:42 ? 00:00:00 [events/0] root 10 2 0 10:42 ? 00:00:00 [events/1] root 11 2 0 10:42 ? 00:00:00 [khelper] root 17 2 0 10:42 ? 00:00:00 [async/mgr] root 155 2 0 10:42 ? 00:00:00 [kintegrityd/0] root 156 2 0 10:42 ? 00:00:00 [kintegrityd/1] root 158 2 0 10:42 ? 00:00:00 [kblockd/0] root 159 2 0 10:42 ? 00:00:00 [kblockd/1] root 161 2 0 10:42 ? 00:00:00 [kacpid] root 162 2 0 10:42 ? 00:00:00 [kacpi_notify] root 163 2 0 10:42 ? 00:00:00 [kacpi_hotplug] root 253 2 0 10:42 ? 00:00:00 [ata/0] root 254 2 0 10:42 ? 00:00:01 [ata/1] root 255 2 0 10:42 ? 00:00:00 [ata_aux] root 257 2 0 10:42 ? 00:00:00 [ksuspend_usbd] root 261 2 0 10:42 ? 00:00:00 [khubd] root 264 2 0 10:42 ? 00:00:00 [kseriod] root 333 2 0 10:42 ? 00:00:00 [khungtaskd] root 356 2 0 10:42 ? 00:00:00 [pdflush] root 357 2 0 10:42 ? 00:00:00 [pdflush] root 358 2 0 10:42 ? 00:00:01 [kswapd0] root 412 2 0 10:42 ? 00:00:00 [aio/0] root 413 2 0 10:42 ? 00:00:00 [aio/1] root 424 2 0 10:42 ? 00:00:00 [crypto/0] root 425 2 0 10:42 ? 00:00:00 [crypto/1] root 636 2 0 10:42 ? 00:00:00 [kpsmoused] root 642 2 0 10:42 ? 00:00:00 [kstriped] root 645 2 0 10:42 ? 00:00:00 [ksnapd] root 674 2 0 10:42 ? 00:00:00 [usbhid_resumer] root 807 2 0 10:42 ? 00:00:01 [scsi_eh_0] root 808 2 0 10:42 ? 00:00:00 [scsi_eh_1] root 819 2 0 10:42 ? 00:00:00 [scsi_eh_2] root 820 2 0 10:42 ? 00:00:00 [scsi_eh_3] root 822 2 0 10:42 ? 00:00:00 [scsi_eh_4] root 823 2 0 10:42 ? 00:00:00 [scsi_eh_5] root 830 2 0 10:42 ? 00:00:00 [kjournald] root 1275 2 0 10:42 ? 00:00:00 [kgameportd] root 1426 2 0 10:42 ? 00:00:00 [scsi_eh_6] root 1427 2 0 10:42 ? 00:00:00 [scsi_eh_7] root 1628 2 0 10:42 ? 00:00:00 [kauditd] root 1784 2 0 10:42 ? 00:00:00 [kmpathd/0] root 1786 2 0 10:42 ? 00:00:00 [kmpathd/1] root 1787 2 0 10:42 ? 00:00:00 [kmpath_handlerd] root 1829 2 0 10:43 ? 00:00:00 [kjournald2] root 1830 2 0 10:43 ? 00:00:00 [kjournald] root 1831 2 0 10:43 ? 00:00:00 [kjournald] root 1832 2 0 10:43 ? 00:00:00 [kjournald] root 1833 2 0 10:43 ? 00:00:00 [kjournald] root 1834 2 0 10:43 ? 00:00:00 [kjournald] root 1835 2 0 10:43 ? 00:00:00 [kjournald] root 1836 2 0 10:43 ? 00:00:00 [kjournald] root 1841 2 0 10:43 ? 00:00:00 [kjournald2] root 2060 2 0 10:43 ? 00:00:00 [rpciod/0] root 2062 2 0 10:43 ? 00:00:00 [rpciod/1] root 2411 2 0 10:43 ? 00:00:00 [bluetooth] where is klogd? the /proc/kmsg and fs/proc/kmsg.c interface still exists, but I cannot find who uses this facilitiy, and thus transferring the data from the "ring buffer" (as mentioned in Mulyadi's blog) to the syslogd? kernel does changes very fast....:-), or perhaps i missed something.
