Some Ideas about list_entry ()

Some Ideas about list_entry ()-General Linux technology-Linux programming and kernel information. The following is a detailed description. In the past two days, I have been reading the content in linux/list. h. I feel that list_entry () has some advantages. However, it is troublesome to specify the struct type when passing parameters.

Therefore, I want to create a new linked list based on this idea, specifying that struct bclist_head adds a flag to indicate the type of peripheral structure, in addition, struct bclist_head is always placed at the position of the first element (only a simple forced type conversion is required to convert struct bclist_head and peripheral struct ). Defines the peripheral interface users can define the definition of macro and struct, within the maximum number range, as long as the registration can make each macro and struct one-to-one correspondence. In this way, you can add different types of struct at will. (There is no major change, but list_entry () can support different memory models ).
