Konstantin Belousov d2bf64c309 Do not sleep for vnode lock while holding map lock in vm_fault. Try to ... acquire vnode lock for OBJT_VNODE object after map lock is dropped. Because we have the busy page(s) in the object, sleeping there would result in deadlock with vnode resize. Try to get lock without sleeping, and, if the attempt failed, drop the state, lock the vnode, and restart the fault handler from the start with already locked vnode. Because the vnode_pager_lock() function is inlined in vm_fault(), axe it. Based on suggestion by: alc Reviewed by: tegge, alc Tested by: pho		2009-02-08 20:23:46 +00:00
