| 172 | -Why: tasklist_lock protects the kernel internal task list. Modules have | |
| 173 | - no business looking at it, and all instances in drivers have been due | |
| 174 | - to use of too-lowlevel APIs. Having this symbol exported prevents | |
| 175 | - moving to more scalable locking schemes for the task list. | |
