SubjectRe: Oops on 2.2.14 While Doing Direct I/O.

Richard,

Caldera's first 2.3 build had some problems. I picked up a later build,
and the modversions.h file was fixed. This was a Caldera Linux
Distribution problem on their early 2.3 (I get early CD's from them
sometimes). When I tried it with RedHat Linux, it worked fine.
kmalloc() not being exported was kindof funny looking to me as well. :)

Thanks for the help.

Your friend,

Jeff
