[OpenAFS] afsd, openafs 1.1.1, linux kernel 2.4.9, Pentium problem

[Derek Atkins]

This is probably the "'struct inode' changed in 2.4.7" problem.
Make sure that src/afs/LINUX/osi_vfs.h matches the struct inode
definition.  IIRC, there was a new semaphore added; you need to
add one to the AFS code to match.
