| Hey Guys,
| Thanks for the help so far. I am wondering after reading the btrfs
| code for certain functions there seem to
| be a lot of u64 variable and function returns of this type. Is this
| common in file system due to the disk
| being in a certain format and depending on the CPU being big or small
| endian that this needed to not reorder
| the disk parts that are being read into main memory and preserve the data's ordering?
| Cheers Nick 
`----
on disk format is little-endian.

have a look at https://btrfs.wiki.kernel.org/index.php/Main_Page for
more information. 

kind regards
