Hi all, I have not seen a struct define inside a function in kernel code and couldn't find any guidelines if it's permitted or frowned upon?
int fn(int i) { struct my_struct { int var1; int var2 }; /* is this allowed? */ struct my_struct struct_local;
Yes, it is allowed, but usually you never want to do that in a kernel function as structures are normally used across functions, not just only in a single one. Do you have a real-world example where you feel this pattern is the best? thanks, greg k-h
