4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hou Tao <houtao1@xxxxxxxxxx> commit 4dd2eb633598cb6a5a0be2fd9a2be0819f5eeb5f upstream. After successful IO or permanent error, b_first_retry_time also needs to be cleared, else the invalid first retry time will be used by the next retry check.
