Partition size limit of UBIFS?

Partition size limit of UBIFS?

[Xing Qianqian]

Hi, All

  As we know, MTD has partition size limit of 2G. Do you know the size limit
of UBIFS partition and file size? 

  Thanks in advance.

I think it is much larger now, after we converted offsets and sizes to
64-bit variables.

I'm too lazy to look at ubifs-media.h, but all sizes are 64-bit
variables there. But I never tested UBIFS on really large UBI volumes.
Never believe theoretical limits - test.

2.6.28 is ancient. I do not remember the veriosn, try 'git log
drivers/mtd'
