driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC9UQB CVE: NA ---------------------------------------------------------------------- The uacce supports device isolation feature. If the driver supports the isolate_err_threshold_read and isolate_err_threshold_write operations, uacce creates a sysfs file. Users can read and configure isolation strategy by sysfs. The sysfs file is created when isolate_err_threshold_read or isolate_err_threshold_write exists, which may cause panic. The sysfs is created only when both isolate_err_threshold_read and isolate_err_threshold_write exist.
