/*
* The device-mapper userspace log module consists of a kernel component and
* a user-space component. The kernel component implements the API defined
* in dm-dirty-log.h. Its purpose is simply to pass the parameters and
* return values of those API functions between kernel and user-space.
*
* Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
* These request types represent the different functions in the device-mapper
* dirty log API. Each of these is described in more detail below.
*
* The user-space program must listen for requests from the kernel (representing
* the various API functions) and process them.
*
* User-space begins by setting up the communication link (error checking
* removed for clarity):
* fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
* addr.nl_family = AF_NETLINK;
* addr.nl_groups = CN_IDX_DM;
* addr.nl_pid = 0;
* r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
* opt = addr.nl_groups;
* setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
*
* User-space will then wait to receive requests form the kernel, which it
* will process as described below. The requests are received in the form,
* ((struct dm_ulog_request) + (additional data)). Depending on the request
* type, there may or may not be 'additional data'. In the descriptions below,
* you will see 'Payload-to-userspace' and 'Payload-to-kernel'. The
