From: Zheng Zengkai <zhengzengkai@huawei.com> From: Geliang Tang <geliang.tang@suse.com> stable inclusion from stable-v6.6.2 commit e8b45937c82d51dc133e015e5e9423f8bd86a668 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 9168ea02b898d3dde98b51e4bd3fb082bd438dab upstream. The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's 1, wait_rm_addr/sf will never break, and will loop ten times, then 'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long, which can sometimes make the tests fail. A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain the current value, and then pass into wait_rm_addr/sf.
