Ok.
Greg, could you accept a backport a new API parameter for PTRACE_GETREGSET/PTRACE_SETREGSET to 4.19 LTS branch?
Fix the problem properly and put a proper Fixes tag on it and worry about the backport later.
Thanks,
tglxI wouldn't worry about backporting to the 4.19 kernel. It's essentially prehistoric for RISC-V. There's no device tree support for any hardware. Also, 4.19 will be going EOL very soon (December 2024).
Ok, I will work on preparing a new patch to add a new set in PTRACE_GETREGSET/PTRACE_SETREGSET.
