Alan Cox acd11c7499 Introduce vm_fault_hold() and use it to (1) eliminate a long-standing race ... condition in proc_rwmem() and to (2) simplify the implementation of the cxgb driver's vm_fault_hold_user_pages(). Specifically, in proc_rwmem() the requested read or write could fail because the targeted page could be reclaimed between the calls to vm_fault() and vm_page_hold(). In collaboration with: kib@ MFC after: 6 weeks		2010-12-20 22:49:31 +00:00
