We don't really need the field names to be globally unique, it is enough
|
|
when they are unique in the given struct. Since structs do not generally
|
|
span mutliple files, using the line number is enough to ensure an unique
|
|
identifier. It means that we can't use two RH_KABI_RENAME macros on the same
|
|
line but that's not happening anyway.
|
|
|
|
This allows pahole to deduplicate the type info of structs using kABI
|
|
macros, lowering the size of vmlinuz from 26M to 8.5M.
