Hi. I found a suspected race condition bug at fs/locks/__posix_lock_file() in recent Linux kernel. This bug is similar to the one reported in ChangeLog 2.6.24 ( commit 85c59580b30c82aa771aa33b37217a6b6851bc14 ). Big Kernel Lock(BKL) might be released and re-taken at the call site of locks_delete_lock() since Releasing-On-Block semantics of BKL. Locks_delete_lock() may be blocked by kmem_cache_alloc() invocation. Please examine the possbility of race condition of this code and let me know your opinion. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
