...is looks correct. We are not deleting head but first entry in 'req_list' which is device corresponding list of pending requests. Please see below: /** * Retrieve the first list entry for the given list pointer. * * Example: * struct foo *first; * first = list_first_entry(&bar->list_of_foos, struct foo, list_of_foos); * * @param ptr The list head * @param type Data type of the list element to retrieve * @param member Member name of the struct list_head field in the list element. * @return A pointer to the first list element. */ #define list_first_entry(ptr, type, member) \...
