The PNP ACPI scan handler device ID list includes all the IDs from

For those IDs, the coressponding devices will never be

Firstly, it isn't necessary to hold lock of vblk-vq_lock
when notifying hypervisor about queued I/O.
Secondly, virtqueue_notify() will cause world switch and
it may take long time on some hypervisors(such as, qemu-arm),
so it isn't good to hold the lock and block other vCPUs.

Dear experts,
I came across a memory/mutex issue. Would you kindly shed some light on it?
I use pthread_mutex_xxx API to protect processes in user space. Since
it should be process shared, I allocated a shared memory to store
pthread_mutex_t structure.
The shared memory is allocated using

For ioremapped efi memory aka old_map the virt addresses are not persistant
across kexec reboot. kexec-tools will read the runtime maps from sysfs then
pass them to 2nd kernel and assuming kexec efi boot is ok. This will cause
kexec boot failure.
To address this issue do not export runtime maps
