Some months ago, I tried to write a 64-bit filesystem working on 32-bit machines and the only real problems were:
- There is no way how to report 64-bit file sizes to user space. - mmap - There is no llseek hook -- the only way how to seek is to let the generic code set f_pos.
It would be very nice to have at least partial 64-bit file support in 2.2 (i.e., no mmap) as some of apps I run (especially my search engine) rely need multi-gigabyte files.
