2006-06-23[PATCH] Add a sysfs file to determine if a kexec kernel is loadedJeff Moyer
Create two files in /sys/kernel, kexec_loaded and kexec_crash_loaded. Each file contains a simple boolean value indicating whether the relevant kernel has been loaded into memory. The motivation for this is geared around support. Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Cc: "Eric W.

2006-03-24[PATCH] fix build error if CONFIG_SYSFS=nAndrew Morton
uevent_seqnum and uevent_helper are only defined if CONFIG_HOTPLUG=y, CONFIG_NET=n. (I stole this back from Greg's tree - it makes allnoconfig work). Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-03-20[PATCH] kobject: fix build error if CONFIG_SYSFS=nJun'ichi Nomura
Moving uevent_seqnum and uevent_helper to kobject_uevent.c because they are used even if CONFIG_SYSFS=n while kernel/ksysfs.c is built only if CONFIG_SYSFS=y, Signed-off-by: Jun'ichi Nomura <j-nomura@ce.jp.nec.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-10[PATCH] kdump: export per cpu crash notes pointer through sysfsVivek Goyal
- Kexec on panic functionality allocates memory for saving cpu registers in case of system crash event. Address of this allocated memory needs to be exported to user space, which is used by kexec-tools. - Previously, a single /sys/kernel/crash_notes entry was being exported as memory allocated was a single continuous array. Now memory allocation being dyanmic and per cpu based, address of per cpu buffer is exported through "/sys/devices/system/cpu/cpuX/crash_notes" Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-01-04[PATCH] driver core: replace "hotplug" by "uevent"Kay Sievers
Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] add uevent_helper control in /sys/kernel/Kay Sievers
This deprecates the /proc/sys/kernel/hotplug file, as all this stuff should be in /sys some day, right? :) In /sys/kernel/ we have now uevent_seqnum and uevent_helper. The seqnum is no longer used by udev, as the version for this kernel depends on netlink which events will never get out-of-order. Recent udev versions disable the /sbin/hotplug helper with an init script, cause it leads to OOM on big boxes by running hundreds of shells in parallel. It should be done now by: echo "" > /sys/kernel/uevent_helper (Note that "-n" does not work, cause neighter proc nor sysfs support truncate().)

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
