While working on extended rand for last_error/first_error timestamps, I noticed that the endianess is wrong, we access the little-endian fields in struct ext4_super_block as native-endian when we print them.
This adds a special case in ext4_attr_show() and ext4_attr_store() to byteswap the superblock fields if needed.
In older kernels, this code was part of super.c, it got moved to sysfs.c in linux-4.4.
