[PATCH 0/5] firewire: cdev: refactor for bus reset event filling

[Takashi Sakamoto]

Hi,

In the cdev layer, there are two places where bus reset events are filed;
the update path for the associated fw_device instance and the get_info
ioctl call. There is still some code that can be refactored in these
paths.

This series refactors the code to make the memory ordering and locking
scope more explicit, and adds a KUnit test for the bus reset event UAPI
structure.

Takashi Sakamoto (5):
  firewire: cdev: use memory barrier to access fw_device members
  firewire: cdev: refactor using scoped_guard() for get_info ioctl call
  firewire: cdev: refactor copy_to_user() in get_info ioctl call
  firewire: cdev: add annotations and comments about race condition of
    bus_reset_closure
  firewire: cdev: add KUnit test for bus reset event UAPI structure
