Description
A flaw was found in the Linux kernel, caused by an incorrect lock ordering between a directory entry and its parent directory in the kernel’s Ceph filesystem implementation; the expected behavior is for the parent directory to always lock before its child. While the associated deadcode isn't actively used, it presents a risk of deadlock which could potentially cause system instability or crashes.
