  firewire: core: reallocate buffer for FCP address handlers when more than 4 are registered (2025-08-03 21:20:15 +0900)

----------------------------------------------------------------
firewire fixes for v6.17-rc1

This set of fixes includes a solution for the issue described in the tag
annotation for v6.17 updates.

The issue involved a potential call to schedule() within an RCU read-side
critical section. The solution applies reference counting to ensure that
handlers which may call schedule() are invoked safely outside of the
critical section.

----------------------------------------------------------------
Takashi Sakamoto (4):
      firewire: core: use reference counting to invoke address handlers safely
      firewire: core: call handler for exclusive regions outside RCU read-side critical section
      firewire: core: call FCP address handlers outside RCU read-side critical section
      firewire: core: reallocate buffer for FCP address handlers when more than 4 are registered
