Thread credentials are maintained as follows: each thread has a pointer to creds and a reference on them. The pointer is compared with proc's creds on userspace<->kernel boundary and updated if needed. This patch introduces a counter which can be compared instead, so that more structures can use this scheme without adding more comparisons on the boundary. |
