[linux-lvm] [compile fix] linux-2.3.99-pre[23]*



Hello,

I noticed a change in patch-2.3.99-pre2 which prevents compiling.
./drivers/block/lvm.c:

@@ -931,8 +931,8 @@
                printk(KERN_DEBUG
                       "%s -- lvm_blk_ioctl -- BLKRAGET\n", lvm_name);
 #endif
-               copy_to_user((long *) arg, &lv_ptr->lv_read_ahead,
-                            sizeof(lv_ptr->lv_read_ahead));
+               if (put_user(lv->lv_read_ahead, (long *)arg))
+                       return -EFAULT;
                break;

I changed 
+               if (put_user(lv->lv_read_ahead, (long *)arg))
to
+               if (put_user(lv_ptr->lv_read_ahead, (long *)arg))


And now i've booted  linux-2.3.99-pre3-3 + patch-2.3.99-pre1-LVM-0.8final
+ lv/lv_ptr fix, and seems to work properly (almost anything on LV's) :)

Greatings,
