Subject: [PATCH V2 0/3] kprobe: Optimize the performance of patching ss
Date: Tue, 13 Sep 2022 11:34:51 +0800 [thread overview]
Message-ID: <20220913033454.104519-1-liaochang1@huawei.com> (raw)
Single-step slot would not be used until kprobe is enabled, that means
no race condition occurs on it under SMP, hence it is safe to pacth ss
slot without stopping machine.
v2:
Backport riscv patch to cksy and arm64.

riscv/kprobe: Optimize the performance of patching single-step slot
csky/kprobe: Optimize the performance of patching single-step slot
arm64/kprobe: Optimize the performance of patching single-step slot
