内核缺陷

## 环境信息 【OS版本】openEuler-22.03-LTS-SP3 【内核版本】kernel-5.10.192，kernel-5.10.272 【硬件平台】Inspur CS5280H2 服务器型号  处理器型号：  内存：  磁盘：  网卡：  BIOS  【组网信息】（和网络、性能相关的问题，应该说明详细的组网和场景信息） 单机 ## 缺陷信息 【问题复现步骤】 1. 制作bcache设备 make-bcache -B /dev/sda -C /dev/nvme0n1p1 --wipe-bcache --force --writeback 2. 对bcache块设备执行fio 随机写操作，缓存可用容量小于80%后，停止fio写操作。 3. 执行对nvme0n1p1的pci remove操作 4. 等待bcache设备停止，系统dmesg出现bcache0 stoped日志。 5. 使用udevadm trigger && udevadm settle触发bcache重新注册。或者使用/lib/udev/bcache-register /dev/sda && /lib/udev/bcache-register /dev/nvme0n1p1注册重新bcache设备。 6. lsblk检查bcache设备正常后，再次对bcache设备进行写操作。 【实际结果】请描述出问题的结果和影响 系统重启，并触发kdump机制生成vmcore 【期望结果】请描述出期望的结果和影响 系统稳定运行 【其他相关附件信息】比如 syslog、dmesg、panic、lockup、kdump 信息、图片等 ``` [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-5.10.0-272.0.0.174.ile2312sp1.x86_64 root=UUID=f7b27f63-9a65-430e-bb24-a509db664875 ro cgroup_disable=files apparmor=0 crashkernel=512M console=ttyS0,115200 net.ifnames=1 biosdevname=0 scsi_mod.scan=sync [ 0.000000] cgroup: Disabling files control group subsystem [ 2524.769073] bcache: bch_count_io_errors() nvme0n1p1: IO error on reading dirty data from cache, recovering.

## 环境信息 【OS版本】openEuler-22.03-LTS-SP3 【内核版本】kernel-5.10.192，kernel-5.10.272 【硬件平台】Inspur CS5280H2 服务器型号  处理器型号：  内存：  磁盘：  网卡：  BIOS  【组网信息】（和网络、性能相关的问题，应该说明详细的组网和场景信息） 单机 ## 缺陷信息 【问题复现步骤】 1. 制作bcache设备 make-bcache -B /dev/sda -C /dev/nvme0n1p1 --wipe-bcache --force --writeback 2. 对bcache块设备执行fio 随机写操作，缓存可用容量小于80%后，停止fio写操作。 3. 执行对nvme0n1p1的pci remove操作 4. 等待bcache设备停止，系统dmesg出现bcache0 stoped日志。 5. 使用udevadm trigger && udevadm settle触发bcache重新注册。或者使用/lib/udev/bcache-register /dev/sda && /lib/udev/bcache-register /dev/nvme0n1p1注册重新bcache设备。 6. lsblk检查bcache设备正常后，再次对bcache设备进行写操作。 【实际结果】请描述出问题的结果和影响 系统重启，并触发kdump机制生成vmcore 【期望结果】请描述出期望的结果和影响 系统稳定运行 【其他相关附件信息】比如 syslog、dmesg、panic、lockup、kdump 信息、图片等 ``` [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-5.10.0-272.0.0.174.ile2312sp1.x86_64 root=UUID=f7b27f63-9a65-430e-bb24-a509db664875 ro cgroup_disable=files apparmor=0 crashkernel=512M console=ttyS0,115200 net.ifnames=1 biosdevname=0 scsi_mod.scan=sync [ 0.000000] cgroup: Disabling files control group subsystem [ 2524.769073] bcache: bch_count_io_errors() nvme0n1p1: IO error on reading dirty data from cache, recovering.
