Detecting RCU Usage Bugs

Explore techniques for detecting RCU (Read-Copy-Update) usage bugs in a 28-minute conference talk from the Linux Plumbers Conference. Dive into the complexities of RCU implementation, learn about runtime detection methods, and discover how to leverage Intel's non-canonical addressing and general protection fault handler for unlimited watchpoints. Gain insights into reviewing RCU usage, understanding correctness and consistency issues, and exploring concepts like lockset conversion, watch point ranges, and poison points. Ideal for developers involved in RCU code review and architecture enthusiasts interested in advanced debugging techniques for concurrent programming.
