Currently perf kmem shows total (page) allocation stat by default, but
sometimes one might want to see live (total alloc-only) requests/pages

Currently it ignores operator priority and just sets processed args as a

The perf kmem command records and analyze kernel memory allocation
only for SLAB objects. This patch implement a simple page allocator
analyzer using kmem:mm_page_alloc and kmem:mm_page_free events.
It adds two new options of --slab and --page. The --slab option is
for analyzing SLAB allocator
It perf kmem support caller statistics for page. Unlike slab case,
the tracepoints in page allocator don't provide callsite info. So
it records with callchain and extracts callsite info.
Note that the callchain contains several memory allocation functions
which has no meaning for users. So
Hello,
Currently perf kmem command only analyzes SLAB memory allocation. And
I'd like to introduce page allocation analysis also. Users can use
--slab and/or --page option to select it. If none of these options
are used, it does slab allocation analysis for backward compatibility.

Currently perf kmem command will select --slab if neither --slab nor
--page is given for backward compatibility. Add kmem.default config
option to select the default value ('page' or 'slab').
# cat ~/.perfconfig
[kmem]
default = page
# perf kmem stat

As do I.

some of the tests that don't have them,
This driver mediates access between the connected CPLD and other devices
on the bus.
The m25p80-compatible boot flash and (some models) MMC use regular SPI,
bitbanged as required by the SoC. However the SPI-connected CPLD has
a "fast write" mode, in which two bits are transferred by SPI clock
The SPI-connected CPLD chip controls access to the main NAND flash
chip and five LEDs.

On modern systems the regulator hierarchy can get quite long and nested
with regulators supplying other regulators. In some cases when debugging
it might be nice to get a tree of these regulators, their consumers
and the regulation constraints in one go.

This patch series increase security of suspend and hibernate actions. It allows
user to safely wipe crypto keys before suspend and hibernate actions starts
without race conditions on userspace process with heavy I/O.
To automatically wipe cryto key for before hibernate action call:
$ dmsetup
This patch adds dm message commands and option strings to optionally wipe key
from dm-crypt device before entering suspend or hibernate state.
Before key is wiped dm device must be suspended. To prevent race conditions with
I/O and userspace processes, wiping action must be called after processes
This patch exports function dm_suspend_md() which suspend mapped device so other
kernel drivers can use it and could suspend mapped device when needed.

Keep a pointer to associated me client in the host client object to
eliminate me client searches. Check if the me client is active in the
firmware by checking if its is linked on the me clients list
Add accessors for the me client properties from host client.
From: Alexander Usyskin
For ME clients that use single receiving buffer
the driver tracks credentials on mei_me_clients structure
for all connections. The driver needs to book keep the shared
resource correctly and track the connections, particularly
the credit has to be cleaned when there is no
Split disconnected state into two parts first reception disconnect
response from the firmware and second actually setting of disconnected
state. Book keeping data are needed for processing and after firmware

Fixed address is simplified FW client that doesn't require
connection and doesn't support flow control.
So it can be only one host client per fixed FW client.
Fixed client access is available only for drivers on mei bus,
connection from user-space is blocked.
Simplify connect state machine by changing the logic around
Connection request in progress - only check if we have a callback in
relevant queue.
Extract common code into mei_cl_send_connect() function

This should be used for debug only.
The feaure is gated by "allow_fixed_address" control exposed in debugfs.

This seems to be missing the corresponding mpt2 updates. Nak to
anything that gets these drivers further out of sync.
Btw, I still need a second ACK for
http://www.spinics.net/lists/linux-scsi/msg82027.html
as well, so we can start getting rid of this duplication mess.

Dear Friend,
I'm happy to inform you about my success in getting the fund
transferred under the cooperation of a new partner from London.
Presently I'm in London for investment projects with my own share of
the total sum. Meanwhile, I didn't forget your past efforts

We've already got scsi_cmd_priv to cover this.

I'd prefer not to expose this to drivers, but if we do it needs to
work for the !mq case.
