Rick Macklem 8fe6bddff7 Forced dismounts of NFS mounts can fail when thread(s) are stuck ... waiting for an RPC reply from the server while holding the mount point busy (mnt_lockref incremented). This happens because dounmount() msleep()s waiting for mnt_lockref to become 0, before calling VFS_UNMOUNT(). This patch adds a new VFS operation called VFS_PURGE(), which the NFS client implements as purging RPCs in progress. Making this call before checking mnt_lockref fixes the problem, by ensuring that the VOP_xxx() calls will fail and unbusy the mount point.
