From 8a78362c4eefc1deddbefe2c7f38aabbc2429d6b Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Fri, 26 Feb 2010 00:20:39 -0500 Subject: block: Consolidate phys_segment and hw_segment limits Except for SCSI no device drivers distinguish between physical and hardware segment limits. Consolidate the two into a single segment limit. Signed-off-by: Martin K.
