Regarding our talk on #xfs, I've been playing with it a while today, and IMHO,
converting xfs_attr_sf_entsize to use struct_size() is ok, although,
entsize_byname, I don't think it's worth it. entsize_byname doesn't get a
xfs_attr_sf_entry as argument, so it will require to change the callers to
actually pass a struct xfs_attr_sf_entry, and the respective sizes, but, some
callers actually don't even have a xfs_attr_sf_entry to pass into it, so IMHO, I
don't think it's worth to change it, but by any means, I'll send today a V2 of
my patchset containing the changes from V1, and adding the struct_size() into
xfs_attr_sf_entry.
Cheers.
