#     dm ioctl: Use struct_size() helper
#     
#     One of the more common cases of allocation size calculations is finding
#     the size of a structure that has a zero-sized array at the end, along
#     with memory for some number of elements for that array. For example:
#     
#     struct dm_target_deps {
#             ...
#             __u64 dev[0];   /* out */
#     };
#     
#     Make use of the struct_size() helper instead of an open-coded version
#     in order to avoid any potential type mistakes.
#     
#     So, replace the following form:
#     
#     sizeof(*deps) + (sizeof(*deps->dev) * count)
#     
#     with:
#     
#     struct_size(deps, dev, count)
#     
#     This code was detected with the help of Coccinelle.
