Shrink UBIFS

[Ryan Meulenkamp]

Hi,


I'm planning to write an ioctl for shrinking a UBIFS to be able to resize the volume its on and create another

volume because it is essential for our upgrade/migration flow. Do you guys have any advice for me? The

hard part is that LEB's that would fall outside the new size should be moved inside the new size. From what

I read, the garbage collection code could be used to  accomplish this, but it is not really possible to define

which LEB's to put where.


Thanks in advance!
