Each driver calling scsi_ioctl() gets an equivalent compat_ioctl()
handler that implements the same commands by calling scsi_compat_ioctl().
The scsi_cmd_ioctl() and scsi_cmd_blk_ioctl() functions are compatible
at this point, so any driver that calls those can do so for both native
and compat mod
Hi Jens, James and Martin,
This series concludes the work I did for linux-5.5 on the compat_ioctl()
cleanup, killing off fs/compat_ioctl.c and block/compat_ioctl.c by moving
everything into drivers.
Overall this would be a reduction both in complexity and line count, but
as I'm also adding docume

virtio-gpu uses cached mappings, set virtio_gpu_gem_funcs.pgprot

In case we have to migrate a ballon page to a newpage of another zone, the
managed page count of both zones is wrong. Paired with memory offlining
(which will adjust the managed page count), we can trigger kernel crashes
and all kinds of different symptoms.
One way to reproduce:
1. Start a QEMU gu
When the driver submits multiple commands in a row it makes sense to
notify the host only after submitting the last one, so the host can
process them all at once, with a single vmexit.
Add functions to enable/disable notifications to allow that. Use the
new functions for primary plane updates.

Hi,

virtio doesn't support dma-buf imports (yet).
So no worries for now.
Why pick writecombine for the imported buffer btw?
It'll probably be correct for the majority of imports,
