[Bug 554009] Re: Resume from disk (swapfile) fails

[Moreno Bartalucci]

Hello,

yes, PAGE_SIZE was one of my concerns too.
I just borrowed those few lines from karmic's resume script, assuming they were correct.
In the meantime I got blkid source code and I made a small program which does the same (check the device and prints the 'type' field) getting the page size from the system through the getpagesize() function.
For some reason, anyway, it works in my system but it doesn't work in the initramfs environment yet.
I need to investigate further on this.
I attach this small program so you can have a view on it.
I'll try to further reduce it and to check why it is not working in the initramfs.

It's usage is: probe devname offset

Offset can be provided or not (if not it assumes offset=0).
It does the calculation getting the page size using getpagesize().

** Attachment added: "Small prog to check and print the type of a block device."
