Date: Mon, 10 May 2010 11:37:27 +0200 From: Marcel Holtmann <marcel@...tmann.org> To: David Miller <davem@...emloft.net> Cc: netdev@...r.kernel.org Subject: [PATCH 37/64] Bluetooth: Optimize SREJ_QUEUE append From: Gustavo F. Padovan <padovan@...fusion.mobi> When the I-frame received is the expected, i.e., its tx_seq is equal to expected_tx_seq and we are under a SREJ, we can just add it to the tail of the list. Doing that we change the complexity from O(n) to O(1). Signed-off-by: Gustavo F.
