- since now we don't need to print error messages if copy_to/from_gpa()
fails, then in many cases we can simplify the function return handling.
In the following example, my fix could change the 'ret' value from
the original '-1' to the actual errno returned from copy_to_gpa(). But
this is valid. Ideally we may replace all '-1' with the actual errno.
- if (copy_to_gpa() < 0) {
- pr_err("error messages");
- ret = -1;
- } else {
- ret = 0;
- }
+ ret = copy_to_gpa();
- in most cases, 'ret' is declared with a default value 0 or -1, then the
redundant assignment statements can be removed.
- replace white spaces with tabs.

ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
