Starting from Linux 4.1, bio_vec will be allowed to pass into filesystem via iter_read/iter_write, so we add a bio_vec field in uio_t to hold it, and use UIO_BVEC in segflg to determine which "vec". Also, to be consistent to newer kernel, we make iovec and bio_vec immutable, and make uio act as an iterator with the new uio_skip field indicating number of bytes to skip in the first segment.

Starting from Linux 4.1 allows iov_iter with bio_vec to be passed into iter_read/iter_write. Notably, the loop device will pass bio_vec to backend filesystem. However, current ZFS code assumes iovec without any check, so it will always crash when using loop device. With the restructured uio_t, we can safely pass bio_vec in uio_t with UIO_BVEC set. The uio* functions are modified to handle bio_vec case separately. The const uio_iov causes some warning in xuio related stuff, so explicit convert them to non const.

System: ArchLinux x86_64 + kernel 4.1.2-2-ARCH + zfs release 0.6.4.2 (commit 44b5ec8)
To reproduce be on zfs filesystem and do:
Last command will introduce one of these situations:
These exceptions aren't catchable over ssh connection (and watching logs), you should are lucky if you catch something.., after rebooting there is nothing in logs.
I also tried formatting image with different filesystems, but nothing changed, even unfomatted image is producing this bug. Only downgrade to kernel 4.0.7 helped me (with same release of zfs module).
Exceptions from my experiments are bellow:
