For a long time, some places in the NFS code have locked/unlocked the NFS node lock with the macros NFSLOCKNODE()/NFSUNLOCKNODE() whereas others have simply used mtx_lock()/mtx_unlock(). Since the NFS node mutex needs to change to an sx lock so it can be held when vnode_pager_setsize() is called, replace all occurrences of mtx_lock/mtx_unlock with the macros to simply making the change to an sx lock in future commit. There is no semantic change as a result of this commit. I am not sure if the change to an sx lock will be MFC'd soon, so I put an MFC of 1 week on this commit so that it could be MFC'd with that commit. Suggested by: kib MFC after: 1 week
