JFFS2 free space

[e***@gdsys.de]

Hello,

I am using ecos together with JFFS2.
Is there any way to find out the free space left in the JFFS2? I had a look at the sources but didn't find any clues.

Regards,
Dirk

I would like to have some kind of basic idea, how much more data could be stored in the JFFS2-filesystem (without considering compression).

While brining up an Intel Mainstone (pxa27x) board I noted that the vfs did not register jffs2 using the mainstream 2.6.8.1/2.6.9-rc2 code.
This may be a well known issue.
If not, this patch below worked for me.
