H A Dnull_blk.hdiff cee1b215 Mon Apr 12 03:55:23 MDT 2021 Max Gurtovoy <mgurtovoy@nvidia.com> null_blk: add option for managing virtual boundary

This will enable changing the virtual boundary of null blk devices. For
now, null blk devices didn't have any restriction on the scatter/gather
elements received from the block layer. Add a module parameter and a
configfs option that will control the virtual boundary. This will
enable testing the efficiency of the block layer bounce buffer in case
a suitable application will send discontiguous IO to the given device.

Initial testing with patched FIO showed the following results (64 jobs,
128 iodepth, 1 nullb device):
IO size READ (virt=false) READ (virt=true) Write (virt=false) Write (virt=true)

Originally we converted bind/unbind to use a new pci bridge driver.
The driver will add/remove _PRT, so we can eventually remove
.bind/.unbind methods.

But we found that some of the _ADR-Based devices don't have _PRT,
i.e. they are not managed by the new ACPI PCI bridge driver.
So that .bind method is not called for some _ADR-Based devices,
which leads to a failure.

Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices

are hot added/removed is also added.

I got the following oops while changing the backlight brightness during
startup. When it happens, it prevents use of the hotkeys, Fn-Fx, and the
lid button.

It's a clear use-before-init, as I verified by testing with an
appropriately-placed "else printk".
