- Btrfs: sysfs compile fixup · b4a2a0ed

```
Just use kobject_set_name(), that works in all kernels (I think...).
Kernels newer than 2.6.23 currently fail with:

- Btrfs: KM_IRQ0 usage in end_io handling · bbf0d006
  Jens Axboe authored Oct 19, 2007
```
endio handling is typically called with interrupts disabled, but can
also be called with it enabled. So save interrupts before using KM_IRQ0
to be completely safe.

  Jens Axboe authored Oct 19, 2007
```
It now returns void and it is never called for partial completions, so
the bio->bi_size check must go.

This allows us to defrag huge directories, but skip the expensive defrag
