[PATCH] Documentation: riscv: Remove KPROBES_ON_FTRACE

Posted by cp0613@linux.alibaba.com 11 months, 2 weeks ago

From: Chen Pei <cp0613@linux.alibaba.com>

Since commit 7caa9765465f60 ("ftrace: riscv: move from REGS to ARGS"),
kprobe on ftrace is not supported by riscv.

And commit 3308172276db5d ("trace: riscv: Remove deprecated kprobe on
ftrace support") removed the relevant code, but left out the
documentation, so fix that.

Perhaps this should have a fixes tag for the commit that removed the
support?
