Hi, A big thanks to everybody who read and replied to first version. I have tried to incorporate reviewer's comments and suggestions.
changelog take1 -> take2 - Rebased 2.6.23 - comment updated - renamed the notifiner name "tunable_notifier" to "tunable_atomic_notifier" - fixed typo These patches add new notifier function and implement it to panic_notifier_list. We used the hardcoded notifier chain so far, but it was not flexible. New notifier is very flexible, because user can change a list of order by debugfs.
