Btrfs: btrfs_check_super_valid: Allow 4096 as stripesize
Older btrfs-progs/mkfs.btrfs sets 4096 as the stripesize. Hence restricting stripesize to be equal to sectorsize would cause super block validation to return an error on architectures where PAGE_SIZE is not equal to 4096. Hence as a workaround, this commit allows stripesize to be set to 4096 bytes. Signed-off-by: Chandan Rajendra <chandan@linux.vnet.ibm.com> Signed-off-by: David Sterba <dsterba@suse.com>
