cdbc107292
This fix the regression introduced by 830427d that it no more creates the FS if disk is small and if no mixed option is provided. This patch will bring it to the original design which will force mixed profile when disk is small and go ahead to create the FS. Which also means that before we open the device for the write we should also check if disk is small. v2: fixes the checkpatch.pl warnings Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
