R. Silva <gustavo@embeddedor.com> # Date: Wed Aug 28 12:31:15 2019 -0500 # # 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. # # Signed-off-by: Gustavo A.
