Add a driver for the A53 Clock Controller. It is a hardware block that
implements a combined mux and half integer divider functionality. It can
choose between a fixed-rate clock or the dedicated A53 PLL. The source

Well a bogus mask shouldn't lead to the warning anyway.
The warning in question is triggered
The crash is observed when a service is being disabled host side while
userspace daemon is connected to the device:
[ 90.244859] general protection fault: [#1] SMP
...
[ 90.800082] Call Trace:
[ 90.800082] [] __fput+0xc8/0x1f0
[ 90.800082] [] fput+0xe/0x10
...
[ 90.800082] []
When Hyper-V host asks us to remove some util driver by closing the
appropriate channel there is no easy way to force the current file
descriptor holder to hang up but we can start to respond -EBADF to all
operations asking it to exit gracefully.
As we're setting hvt->mode from two separate contex
inmsg should be freed in case of on_msg() failure to avoid memory leak.
Preserve the error code from on_msg().

Hi Tiffany,
My apologies for the long delay, but I finally have time to do a review of this
code.

I suggest to make the implementation of the function "mgc_process_recover_log"
a bit more efficient.

Hello,
I've been thinking about this for some time, but didn't have a chance
to properly investigate so far. My question is: why do we even bother
with partial IO in zram?
We set zram->disk->queue->limits.discard_granularity to PAGE_SIZE,
just like the rest of queue configuration, e.g.

Hi Alan,
Thanks for your reply.
Patch is not intended to increase DYNAMIC_MINORS from 64.
The error hadling in misc_register is not perfect.
Ideally, when misc minor number limit exceed then it should return -EBUSY
instead of already
reserved minor number.
For example, in my case value of "i"

Hello all,
I'm trying to execute a user-space binary from a IRQ context so I
started form this module which execute the reboot command. If I adapt
this code to execute command with parameters I see that it silently
