but the problem looks clear: CONFIG_MMU is not set, so we need
a dummy filemap_page_mkwrite() along with generic_file_mmap() and
generic_file_readonly_mmap().
I'll send the fix, but...
Benjamin, Jeff, shouldn't AIO depend on MMU? Or it can actually work even
if CONFIG_MMU=n?

It should work when CONFIG_MMU=n, but I doubt anyone regularly attempts to
do so (if ever).

Really? I am just curious.
alloc_anon_inode() doesn't set S_IFREG, it seems that nommu.c:do_mmap_pgoff()
should just fail in validate_mmap_request() ?
Even if not, it should fail because of MAP_SHARED && !NOMMU_MAP_DIRECT?
I am just trying to understand, could you explain?
Oleg.

I am not saying the code currently does, but that the use of the functionality
is valid. The code clearly doesn't at the moment, and given that nobody
has complained, it's seems unlikely that there are any active users.

Hmm. Confused...
So sys_io_setup() can't succed if CONFIG_MMU=n.
Then why do we allow CONFIG_AIO=y in this case? And it is even
"default y" and needs EXPERT to disable...
But OK, I won't argue. I'll send the fix which fixes the build.
Thanks!
Oleg.
