green 2002/03/18 07:08:10 PST Modified files: sys/vm vm_fault.c vm_glue.c vm_map.c vm_map.h vm_pageout.c vm_zone.c Log: Back out the modification of vm_map locks from lockmgr to sx locks. The best path forward now is likely to change the lockmgr locks to simple sleep mutexes, then see if any extra contention it generates is greater than removed overhead of managing local locking state information, cost of extra calls into lockmgr, etc. Additionally, making the vm_map lock a mutex and respecting it properly will put us much closer to not needing Giant magic in vm.
