Hello, I try to understand why the kernel uses mutex to protect the address_space structure. I checked the critical areas protected by i_mmap_mutex, and didn't see these areas use IO. I don't see why we can't use spin locks. Do I miss something? It seems most of critical areas provided by i_mmap_mutex aren't very large. Thanks, Da _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
