The blkback name is like blkback.domid.xvd[a-z], if domid has four digits
(means larger than 1000), then the backmost xvd wouldn't be fully shown.
Define a BLKBACK_NAME_LEN macro to be 20, enlarge the array size of
blkback name, so it will be fully shown in any case.

You are right, roger. Thanks.
domid is a u16, it will occupy 5 characters at most. So the biggest

At this situation, define BLKBACK_NAME_LEN macro to be 20 is safe.

Add new sort keys for page: page, order, migtype, gfp - existing
'bytes', 'hit' and 'callsite' sort keys also work for page. Note that
-s/--sort option should be preceded by either of --slab or --page

Note that the callchain contains several memory allocation functions

Is this patch getting too big (and getting bigger and bigger) to be ever
merged?
Unless you tell me otherwise, I'm thinking about splitting it into
several patches, one for each subsystem.
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 a
The struct page is opaque for userspace tools, so it'd be better to save
pfn in order to identify page frames.
The textual output of $debugfs/tracing/trace file remains unchanged and
only raw (binary) data format is changed - but thanks to libtraceevent,
userspace tools which deal with the raw dat
Currently perf kmem shows total (page) allocation stat by default, but
sometimes one might want to see live (total alloc-only) requests/pages
only. The new --live option does this by subtracting freed allocation
from the stat.

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 only write Port 1 Control and VLAN configuration since
this will be needed for hardware bridging. More can be added later

Patch 1 to 7 of this series prepare the drivers using the mv88e6xxx code
for HW bridging support, without adding the code itself. For the most part
this factors out common port initialization code. There is no functional

Bridge support is similar for all chips supported by the mv88e6xxx code,
