[PATCH driver-core-linus] kernfs: kernfs_notify() must be useable from non-sleepable contexts
...81025f9f>] arch_cpu_idle+0xf/0x20
[<ffffffff810f5adc>] cpu_startup_entry+0x37c/0x7b0
[<ffffffff8104df1b>] start_secondary+0x25b/0x300
This patch fixes it by punting the notification delivery through a
work item. This ends up adding an extra pointer to kernfs_elem_attr
enlarging kernfs_node by a pointer, which is not ideal but not a very
big deal either. If this turns out to be an actual issue, we can move
kernfs_elem_attr->size to kernfs_node->iattr later.
