There's actually around 900, for ~100:1 ratio $ git grep -P "\bsizeof\s+\w" -- "*.[ch]" | wc -l 907 $ git grep -P "\bsizeof\s*\(" -- "*.[ch]" | wc -l 117203 About half of these occurrences are in 3 paths and their actual uses of sizeof without and with parenthesis are: drivers/infiniband/ 212:3696 drivers/media/ 111:5058 drivers/usb/ 121:2006 > Or perhaps it might be an opportunity during some other changes to > certain users...
