In zfs_write(), the loop continues to the next iteration without accounting for partial copies occurring in uiomove_iov when copy_from_user/__copy_from_user_inatomic return a non-zero status. This results in "zfs: accessing past end of object..." in the kernel log, and the write failing. Account for partial copies and update uio struct before returning EFAULT, leave a comment explaining the reason why this is done.
