A comment on "A circular list-based mutual exclusion scheme for large shared-memory multiprocessor"
Ting‐Lu Huang, Chien-Hua Shann · IEEE Transactions on Parallel and Distributed Systems · 1998
The circular list-based mutual exclusion algorithm proposed by Fu and Tzeng (1997) is subject to a race condition that leads to a deadlock under subtle situations. An execution sequence evidences the race, and a modified version is provided. The performance of the original algorithm remains unchanged.
