Similar to the pstore_info read() callback, there were too many arguments.
This switches to the new struct pstore_record pointer instead. This adds

Implement functions to handle the xenbus handshake. Upon connection,
allocate the rings according to the protocol specification.
Initialize a work_struct and a wait_queue. The work_struct will be used
to schedule work upon receiving an event channel notification from the
backend. The wait_queue wi
Introduce the Xen 9pfs transport driver: add struct xenbus_driver to
register as a xenbus driver and add struct p9_trans_module to register
as v9fs driver.
All functions are empty stubs for now.

Implement struct p9_trans_module create and close functions by looking
at the available Xen 9pfs frontend-backend connections. We don't expect
many frontend-backend connections, thus walking a list is OK.
Send requests to the backend by copying each request to one of the
available rings (each fron
Patch 1 adds a new NMI_LAST call chain that mimics the current NMI_UNKNOWN
call chain except it eliminates the WARNING message about multiple NMI
handlers registering on this call chain.
Patch 2 moves the UV NMI handler from using the NMI_UNKNOWN call chain
to this new NMI_LAST call chain.

Add a new NMI call chain that is called last after all other NMI handlers
have been checked and did not "handle" the NMI. This mimics the current
NMI_UNKNOWN call chain except it eliminates the WARNING message about
multiple NMI handlers registering on this call chain.

Could you please also tell us whether the devoice only has touchpad, or
if it has touchpad/starckstick combo?
Thanks.

Hi all,
This patch series implements a new transport for 9pfs, aimed at Xen
systems.
The transport is based on a traditional Xen frontend and backend drivers
pair. This patch series implements the frontend, which typically runs in
a regular unprivileged guest.
I'll follow up with another series

Hi,
Currently we are having hardware which does not have RTC. It is single
processor system. However it does have TSC timer.
Now, how to use scheduler with only TSC as current kernel scheduler leverage
the RTC for scheduling? I had seen one old patch
