[fuse-devel] The new bmap functionality

[Lars S. <lsk...@im...>]

Hi everyone!

First, many thanks to Miklos Szeredi and Csaba Henk for FUSE itself
and the Python bindings, respectively.

I'm writing a university project entitled 'Paging to Remote
Memory'. Part of the idea was to do it in userspace, to test how much
can really be done with FUSE. I have written a filesystem that
connects via TCP/IP to a remote server and provides memory through
it. Then I ran swapon on the device, and failed. I went looking in the
kernel and found the bmap requirement. As you can guess, I was stuck
for a while :-)

Then this morning I read that Miklos had committed support for the
bmap operation, which was exactly what I needed. But the header file
says "this makes sense only for block device backed filesystems
mounted with the 'blkdev' option." I can see this certainly does not
work with my current code. How would I go about making it work?

Thanks in advance!

Lars
