Date: Wed, 02 Nov 2011 15:14:03 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Mike Christie <michaelc@...wisc.edu>, James Bottomley <JBottomley@...allels.com> Subject: [037/107] [SCSI] libiscsi_tcp: fix LLD data allocation 2.6.32-longterm review patch. If anyone has any objections, please let us know. ------------------ From: Mike Christie <michaelc@...wisc.edu> commit 74dcd0ec735ba9c5bef254b2f6e53068cf3f9ff0 upstream. Have libiscsi_tcp have upper layers allocate the LLD data along with the iscsi_cls_conn struct, so it is refcounted.
