[OpenAFS-devel] porting openafs to another linux - problems with vRefcount type.. .

[Neulinger, Nathan]

I've got it mostly building, except for anything to do with reference
counts:

../afs/afs_callback.c:160: incompatible types in assignment
make[1]: *** [afs_callback.o] Error 1

Those are almost all (or all) references to vnhold or similar, which
increments the reference count.

If I change vrefCount to vrefCount.counter they get past the error. (Or
simpler, if I add .counter to the references to i_count in osi_vfs.h.) I've
got it ifdef'd currently, but I'm curious as to why this is necessary.

What is going on special on parisc-linux (or on i386_linux) that allows it
to work on one, but not on the other? Both look to have the same definition
for atomic_t.
