Hi, from the kernel point of view, how can I understand if a memory page is locked? I'll explain better my question by means of an example. I've two or more threads that, obviously, share some memory regions (so some memory pages). It can happens that one of these threads locks a memory page. Is there a way to view that this page is locked by looking at the struct page fields of this memory page? Is there a way to understand if another thread is trying to access to this locked page? If so, it occurs page fault in this case? with wath error value? Thanks. Vincenzo Mallozzi.
