Hi Folks,

I am inside a file system driver, a modified version of vfat to be 
exact, trying to get vendor info that uniquely identifies a USB storage 
device that's associated.  I have the device name coming into 
vfat_get_sb().  I looked down through the associated structures I get 
here but nothing obvious pops out.  What's the best way to get down to 
the vendor/unique device info from here?  Thanks in advance for your 
help and apologies in advance if this is a dumb question.

Regards,

-- Robert.

Do this from userspace, with the tools provided in the udev package,
vol_id and friends.

Why would you want to do this within the kernel?

thanks,

Please don't use html, the linux-kernel list will reject it.

But you would do that from userspace right?

What block driver would be able to look into the file system contents?

What driver needs this to be added to it?

thanks,
