[@pxolqopt3597]

As you probably know C doesn't have a concept of RAII so you have to manually clean up resources you allocate and create, and just using goto to jump to a common exit block is just an easy way to not forget to clean up after yourself. It is probably much more important in the kernel (i might be wrong) since none of these resources will be auto cleaned up (again, might be wrong about this) by the kernel like they are when your user space process terminates.

[@whyareyoulookingatthislol]

yeah I've seen my professor use goto to jump forward to cleanup code

[@jthoward]

Yeah even Torvalds says it’s common kernel practice

[@XeZrunner]

I used it in a C university assignment once. We were told goto is not a good practice, but it has its uses. Some modern languages now have the option to specify which loop you want to 'break' out of or 'continue' in. In C, you can define labels and jump to the points you wish, which lets you achieve the same result. It shouldn't be feared to the point that languages omit it entirely, it definitely has its uses.
