There are a lot of different structures that need to have a "frozen" abi for the next 5+ years. Add padding to a lot of them in order to be able to handle any future changes that might be needed due to LTS and security fixes that might come up. It's a best guess, based on what has happened in the past from the 5.10.0..5.10.110 release (1 1/2 years). Yes, past changes do not mean that future changes will also be needed in the same area, but that is a hint that those areas are both well maintained and looked after, and there have been previous problems found in them. Also the list of structures that are being required based on OEM usage in the android/ symbol lists were consulted as that's a larger list than what has been changed in the past. Hopefully we caught everything we need to worry about, only time will tell... Bug: 151154716 Change-Id: I880bbcda0628a7459988eeb49d18655522697664 Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
