From 5dee2477df5368368b7dba810a17a3c411a1d0f0 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Mon, 21 Sep 2009 21:46:05 +0200 Subject: [PATCH] block: Do not clamp max_hw_sectors for stacking devices Stacking devices do not have an inherent max_hw_sector limit. Set the default to INT_MAX so we are bounded only by capabilities of the underlying storage. Signed-off-by: Martin K.
