Dokan does not work with Visual C++ Express (Paging IO problems)

[GoogleCodeExporter]

Dokan does not honor the IRP flag IRP_PAGING_IO and the file object flag
FO_SYNCHRONOUS_IO. 
When doing paging IO or asynchronous IO, the file pointer should not be moved. 

See: http://www.osronline.com/article.cfm?article=17#Q29

I have attached two patches for sys and dokan below

Than you for your patch. I changed the driver to handle current byte offset 
correctly.
BTW, do we need to notify paging IO to user mode?

Yes, I believe so. I've read somewhere that paging IO might cause writes beyond 
the
end of file position. These writes should be ignored.

I changed to notify paging io. I couldn't fix this issue for a log time, thank 
you so 
much.
