I am trying to implement the rethook of the arm64 platform, referring to the code of other architectures, it can already run normally on the v6.1 branch, but after commit 26299b3f6ba2 ("ftrace: arm64: move from REGS to ARGS"), regs is no longer supported, resulting in CONFIG_FPROBE is also not supported (although RETHOOK is implemented). I try to revert the patch, and kprobe.multi can be run correctly. Now, what should I do? Should I roll back this patch or find a way to run fprobe without regs? Any help is welcome. -- Jackie Liu _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
