From 00c4a09bb0840457f5f8f5753a562e5e19a91baf Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Wed, 14 Dec 2011 13:46:23 -0200 Subject: [SCSI] libcxgbi: do not print a message when memory allocation fails In alloc_pdu, libcxgbi tries to allocate a skb with GFP_ATOMIC, which may potentially fail. When it happens, the current code prints a warning message. When the system is under IO stress, this failure may happen lots of times and it usually scares users. Instead of printing the warning message, the code now increases the tx_dropped statistics for the ethernet interface wich is doing the iscsi task.
