osi_file - large space instead of small space
osi_modile - which symbol is looked for

misc changes in signal handling and sleeping

in vfsops - a PutVCache for afs_globalVp was added if afs_globalVp was
non null. 

vattr2inode call was changes from AFSTOI from AFSTOV

file read buffering changes for AFS_64BIT_CLIENT in osi_vnodeops.c,
related to a patch from hartmut for large file support. 

changes to do logs on tdc instead of avc...

some changes for @sys handling...



I sure don't see anything jumping out at me that screams problem, but
I'm also not really in tune with kernel internals. 



printf'ing the hell out of the afs/LINUX/ code yields information that
it's never even getting to anything in vnodeops... Really the only thing
that appears to get touched is afs_root in osi_vfsops.c, and it all
looks pretty normal. 

I'm set up to easily test stuff for this at the moment, so if you've got
any place you want me to look at, holler.
