R. Silva <gustavo@embeddedor.com> # Date: Mon Jun 10 16:00:38 2019 -0500 # # libnvdimm, region: Use struct_size() helper in kzalloc() # # 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 nd_region { # ... # struct nd_mapping mapping[0]; # }; # # instance = kzalloc(sizeof(struct nd_region) + sizeof(struct nd_mapping) * # count, GFP_KERNEL); # # Instead of leaving these open-coded and prone to type mistakes, we can # now use the new struct_size() helper: # # instance = kzalloc(struct_size(instance, mapping, ndr_desc->num_mappings), # GFP_KERNEL); # # This code was detected with the help of Coccinelle. # # Signed-off-by: Gustavo A.
