Thanks for the patch! Reading a file on an ext4 file system located on a partition starting beyond the 2TiB limit on a SATA hard disk attached to a CuBox Pro works fine now. Tested-by: Sascha Silbe <t-ub...@infra-silbe.de> You'll probably have to add your Signed-off-by before your patch can be merged. A minor nitpick: The limit is at 2TiB (2^41 Bytes), which is roughly 2.2TB (2.2 * 10^12 Bytes). Sascha
