From 7eb333fbdde32dbebdcc88c35610159e207237c9 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Tue, 14 Jul 2015 14:57:55 -0700 Subject: [PATCH] Linux 4.2 compat: remove bio->bi_cnt access Linux 4.2 commit torvalds/linux@dac5621 renamed bio->bi_cnt to bio->__bi_cnt. Because this value is only used once in a block of debug code it simplest just to remove the PANIC. To my knowledge this debugging has never been hit or proved useful so this is no great loss.
