IAM in ldiskfs-osd will always consume some slots in bh_lru (see: fs/buffer.c), if we keep buffer_head reference on root node, we can save one slot in bh_lru and could be somehow helpful for overall performance, I did some tests, LRU hits increased 5%-10% while creating files if we always keep this reference.
I'm not expert of this, so please post your comment here if it's totally wrong to do this.
