This version of sg for the lk 2.5 series re-adds direct IO
support using work done by Kai Makisara (on st driver, posted
2002/7/29).
Changelog:
Changes since 3.5.26 (20020708)
- re-add direct IO using Kai Makisara's work
- re-tab to 8, start using C99-isms
- simplify memory management
Like Kai's patch, this one needs kernel/ksyms.c altered
to export get_user_pages(). Kai's worker routines
st_map_user_pages() and st_unmap_user_pages() are duplicated
as is. Hopefully these routines will find a home in
a library soon.
The re-tabbing makes the patches rather large so here
are 2 urls:
This tarball contains sg.h and sg.c

This gzipped patch is against lk 2.5.31 and touches
kernel/ksyms.c as well
http://www.torque.net/sg/p/sg_3527_lk2531.diff.gz
Testing is ongoing, everything works apart from "zero
copy" copy. That uses mmap-ed IO on the read side and
direct IO on the write side. Not too many people would
be using that I suspect.
