[RFC PATCH v3 01/36] *** HACK *** linux-headers: Update headers to pull in TDX API changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pull in recent TDX updates, which are not backwards compatible.

It's just to make this series runnable. It will be updated by script

	scripts/update-linux-headers.sh

once TDX support is upstreamed in linux kernel.
