- * The dquot is already being flushed. It may have been
- * flushed delayed write, however, and we don't want to
- * get stuck waiting for that to complete. So, we want to check
- * to see if we can lock the dquot's buffer without sleeping.
- * If we can and it is marked for delayed write, then we
- * hold it and send it out from the push routine. We don't
- * want to do that now since we might sleep in the device
- * strategy routine. We also don't want to grab the buffer lock
- * here because we'd like not to call into the buffer cache
- * while holding the AIL lock.
- * Make sure to only return PUSHBUF if we set pushbuf_flag
- * ourselves. If someone else is doing it then we don't
- * want to go to the push routine and duplicate their efforts.
+ * dquot has already been flushed to the backing buffer,
+ * leave it locked, pushbuf routine will unlock it.
