From 29fc7e3e70a05e9eea28afb6707a39c1a53e2f66 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 3 Feb 2006 03:03:41 -0800 Subject: [PATCH] md: Assorted little md fixes - version-1 superblock + The default_bitmap_offset is in sectors, not bytes. + the 'size' field in the superblock is in sectors, not KB - raid0_run should return a negative number on error, not '1' - raid10_read_balance should not return a valid 'disk' number if ->rdev turned out to be NULL - kmem_cache_destroy doesn't like being passed a NULL.
