Hi,
using unionfs (cvs or newer snapshots) on a Fedora Core 5 system,
I get the following compile error:
cc1: warnings being treated as errors
/root/unionfs-tests/tmp/build/unionfs/mmap.c:338: warning:
initialization from incompatible pointer type
It appears that the sync_page function in struct
address_space_operations is expected to return an int,
(at least in a vanilla 2.6.16), whereas the
unionfs_sync_page function returns void.
The attached trivial patch fixes the problem.
Regards,
Torsten
