Subject: [PATCH net-next 0/6] net/mlx5: Move notifiers outside the devlink lock

Hi,

This series by Cosmin moves blocking notifier registration in the mlx5
driver outside the devlink lock during probe.

This is mostly a no-op refactoring that consists of multiple pieces.
It is necessary because upcoming code will introduce a potential locking
cycle between the devlink lock and the blocking notifier head mutexes,
so these notifiers must move out of the devlink-locked critical section.

Regards,
Tariq
