devlink: Allow taking device lock in pre_doit operations 2023-11-18T17:38:50+00:00 Ido Schimmel idosch@nvidia.com 2023-11-15T12:17:13+00:00 d32c38256db30a2d55b849e2c77342bc70d58c6e Introduce a new private flag ('DEVLINK_NL_FLAG_NEED_DEV_LOCK') to allow netlink commands to specify that they need to acquire the device lock in their pre_doit operation and release it in their post_doit operation. The reload command will use this flag in the subsequent patch. No functional changes intended.
