(CC Alex directly for visibility) Hi Alexey, Thank you for sending the patch over! However, if possible, can you send it as plain text without any multi-part MIME involved? This is as per: https://www.kernel.org/doc/html/latest/process/submitting-patches.html People have scripts to handle patches submissions, plus there is automation that relies on e-mails being just plain text with inline patches. Sorry for the trouble, and thank you for understanding. > Although unlikely, the 'id' value may be as big as 4294967295 > (uint32_max) and "virtfn4294967295\0" would require 17 bytes > instead of 16. If possible, it would be nice to mention that this needed to make sure that there is enough space to correctly NULL-terminate the ID string. Thank you! Krzysztof
