Hello Eric,

This looks fine, but technically 'unsigned int' would be more appropriate here, given the context. If we look at the whole function in 6.12, we can see that it took an 'unsigned int' length:
Ack. Do you want me to send a v2 with `unsigned int` instead?
Sure. Could you also make it clear which kernel version(s) you are expecting the patch to be applied to? Is it everything 5.4 through 6.15? It looks like this bug actually got exposed by f4da7afe07523f ("kexec_file: increase maximum file size to 4G") in 6.0. But backporting to older versions should be fine too, if it applies to them.
