R. Silva <gustavo@embeddedor.com> # Date: Wed Aug 7 11:42:29 2019 -0500 # # perf/x86/intel/uncore: Use struct_size() in kzalloc_node() # # 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 intel_uncore_box { # ... # struct intel_uncore_extra_reg shared_regs[0]; # }; # # size = sizeof(struct intel_uncore_box) + count * sizeof(struct intel_uncore_extra_reg); # instance = kzalloc_node(size, GFP_KERNEL, node); # # Instead of leaving these open-coded and prone to type mistakes, we can # now use the new struct_size() helper: # # instance = kzalloc_node(struct_size(instance, shared_regs, count), GFP_KERNEL, # node); # # Notice that, in this case, variable size is not necessary, hence it # is removed. # # This code was detected with the help of Coccinelle. # # Signed-off-by: Gustavo A.
