I dont know if there is anything wrong with our mmap() solution.
But I am sure that simply removing these lines

.aio_read = generic_file_aio_read,
.aio_write = generic_file_aio_write,

from the dazukofs_main_fops will be sufficient to avoid the bug 
http://lists.gnu.org/archive/html/dazuko-devel/2009-10/msg00002.html
for the reasons I gave in my former post.
IMO this bug has nothing to do with mmap().
