There is an error that can occur where the driver adds the same URB to USB

obviously controls the exclusiveness of rcu_sync_enter(). This is

Yeah. You're right. Doing a vmalloc() when kmalloc() doesn't have even
a tiny sliver of RAM isn't going to work. It's easier to use
libcfs_kvzalloc() everywhere, but it's probably the wrong thing.

MLOCK's debug info, spewed on CDMA timeout, contains meaningless MLOCK

current_pt_regs() sometimes returns regs of the userspace process and in
case of a kernel crash this is not what we need to report. E.g. when we
trigger crash with sysrq we see the following:

When general-purpose kexec (not kdump) is being performed in Hyper-V guest

If some piece of code wants to check kexec_in_progress it has to be put
in #ifdef CONFIG_KEXEC block to not break the build in !CONFIG_KEXEC

We already have hv_synic_free() which frees all per-cpu pages for all

At the very late stage of kexec a driver (which are not being unloaded) can
try to post a message or signal an event. This will crash the kernel as we
already did hv_cleanup() and the hypercall page is NULL.

The guest may have to send a completion packet back to the host.
To support this usage, permit sending a packet without a payload -

The kfree() function was called even if a previous memory allocation
try failed.
This implementation detail could be improved by the introduction
of another jump label.

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
