| |
The attached patch is needed to really allow the thread_info to live in the same chunk of memory as task structure. I missed it in my last patch because the fix was originally keyed on INIT_THREAD_SIZE, which was wrong but resulted in a one-liner patch which was easy to miss. The patch below is cleaner. I suppose it would be nice if we could get rid of INIT_THREAD_SIZE entirely, but it looks like user-mode Linux still relies on it.
