Hi,
The patchset fixes a regression introduced by the following commits:
c7f3888ad7f0 ("switch iov_iter_get_pages() to passing maximal number of pages")
c9c37e2e6378 ("fuse: switch to iov_iter_get_pages()")
The regression manifests itslef like this (thanks to Werner Baumann for
reporting):
> davfs2 uses the fuse kernel module directly (not using the fuse
> userspace library). A user of davfs2 reported this problem
> (http://savannah.nongnu.org/support/?108640):
>
> dd if=/dev/zero of=/mnt/owncloud/test.txt bs=20416 count=1
> works fine, but
> dd if=/dev/zero of=/mnt/owncloud/test.txt bs=20417 count=1
> fails.
Thanks,
Maxim
