* ftrace: ignore functions that cannot be kprobe-edIngo Molnar2008-10-141-1/+1
| | | | | | | | | | kprobes already has an extensive list of annotations for functions that should not be instrumented. Add notrace annotations to these functions as well. This is particularly useful for functions called by the NMI path. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* ipc: re-enable msgmni automatic recomputing msgmni if set to negativeNadia Derbey2008-04-291-0/+38
| | | | | | | | | | | | | | | | | | The enhancement as asked for by Yasunori: if msgmni is set to a negative value, register it back into the ipcns notifier chain. A new interface has been added to the notification mechanism: notifier_chain_cond_register() registers a notifier block only if not already registered. With that new interface we avoid taking care of the states changes in procfs.

* kernel/notifier.c should #include <linux/reboot.h>Adrian Bunk2008-02-061-0/+1
| | | | | | | | | Every file should include the headers containing the prototypes for its global functions (in this case {,un}register_reboot_notifier()).

* Add kernel/notifier.cAlexey Dobriyan2007-10-191-0/+539
There is separate notifier header, but no separate notifier .c file. Extract notifier code out of kernel/sys.c which will remain for misc syscalls I hope. Merge kernel/die_notifier.c into kernel/notifier.c.
