driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I79JRM CVE: NA ---------------------------------------------------------------------- The inode can be different in a container, for example, a docker and host both open the same uacce parent device, which uses the same uacce struct but different inode, so uacce->inode is not enough. What's worse, when docker stopped, the inode will be destroyed as well, causing use-after-free in uacce_remove. So use q->filep->f_mapping to replace uacce->inode->i_mapping.
