Pending analysis

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pstore: inode: Only d_invalidate() is needed<br /> <br /> Unloading a modular pstore backend with records in pstorefs would<br /> trigger the dput() double-drop warning:<br /> <br /> WARNING: CPU: 0 PID: 2569 at fs/dcache.c:762 dput.part.0+0x3f3/0x410<br /> <br /> Using the combo of d_drop()/dput() (as mentioned in<br /> Documentation/filesystems/vfs.rst) isn&amp;#39;t the right approach here, and<br /> leads to the reference counting problem seen above. Use d_invalidate()<br /> and update the code to not bother checking for error codes that can<br /> never happen.<br /> <br /> ---
