| |
Few of the notifier_chain_register() callers use __initdata in the definition of notifier_block data structure. It is incorrect as the data structure should be available after the initializations (they do not unregister them during initializations).
This was leading to oops when notifier_chain_register() call is invoked for those callback chains after initialization.
This patch fixes all such usages to _not_ have the notifier_block data structure in the init data section. -- Signed-Off-By: Chandra Seetharaman <sekharan@us.ibm.com>
