So we just told the user (by returning error on the close) that the
file is bad, but subsequent reads should proceed as everything went
fine? If we can guarantee to obain consistency at a later point, the
close should not have returned failiure in the first place. You can't
have it both ways. Until someone implements disconnected AFS and fixes
the writeback later, I suggest to throw away the data which never will
make it to the server.
