The following commit has been merged in the master branch: commit 6417f03132a6952cd17ddd8eaddbac92b61b17e0 Author: Leon Romanovsky <leonro(a)nvidia.com> Date: Wed Mar 17 12:45:47 2021 +0200 module: remove never implemented MODULE_SUPPORTED_DEVICE MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not.

On error, -1 is returned and *errno* + * is set appropriately. + * + * May set *errno* to **EINVAL**, **EPERM**, **ENOMEM**, or + * **E2BIG**. **E2BIG** indicates that the number of elements in + * the map reached the *max_entries* limit specified at map + * creation time. + * + * May set *errno* to one of the following error codes under + * specific circumstances: + * + * **EEXIST** + * If *flags* specifies **BPF_NOEXIST** and the element + * with *key* already exists in the map. + * **ENOENT** + * If *flags* specifies **BPF_EXIST** and the element with + * *key* does not exist in the map. + * + * BPF_MAP_DELETE_BATCH + * Description + * Delete multiple elements in a map by *key*. + * + * The *keys* parameter is an input parameter which must point + * to memory large enough to hold *count* items based on the key + * size of the map *map_fd*, that is, *key_size* * *count*. + * + * Each element specified in *keys* is sequentially deleted.

The following commit has been merged in the master branch: commit b1de0f01b0115575982cf24c88b35106449e9aa7 Author: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> Date: Sat Feb 13 18:02:04 2021 +0100 batman-adv: Use netif_rx_any_context(). The usage of in_interrupt() in non-core code is phased out. Ideally the information of the calling context should be passed by the callers or the functions be split as appropriate. The attempt to consolidate the code by passing an arguemnt or by distangling it failed due lack of knowledge about this driver and because the call chains are hard to follow. As a stop gap use netif_rx_any_context() which invokes the correct code path depending on context and confines the in_interrupt() usage to core code.
