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 drivers/firewire/core-transaction.c | 91 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++---------- include/linux/firewire.h | 4 ++++ 2 files changed, 85 insertions(+), 10 deletions(-) Regards Takashi Sakamoto
