[RHEL 5]A panic happens because d_delete() and d_invalidate() can operate the same dentry->d_flags at the same time
Issue
- If we delete files and get files statistics concurrently, a system may work incorrectly (Ex. a panic happens).
- For instance, there is a conflict between d_delete() and d_invalidate(). These two function calls can operate same dentry->d_flags at the same time.
Environment
- Red Hat Enterprise Linux 5 Update 2, 3, and 4
