Hi, Please look at https://lore.kernel.org/lkml/CAA42iKx2f2LsAQ9C5rxnCTPhOB6n+L35Winc5WK1K2EySAjvXA@mail.gmail.com/T/#u (local) and see if that matches what you thought you sent as a patch. The gmail web interface is notorious for dropping tabs in emails. On 12/13/22 09:35, Seija K. wrote:
There are many places where "int len = strlen(foo);" is written, just for len to be passed as a parameter of size_t. This causes truncation and then expansion back from int to size_t. Not to mention this is poor logic and needless truncations can add extra unneeded instructions. This patch aims to fix the worst offenders.
