Just set up the show callback in the tty_operations, and use
proc_create_single_data to create the file without additional
boilerplace code.

In-Reply-To: <20180419124140.9309-1-hch@lst.de>
Variants of proc_create{,_data} that directly take a struct seq_operations
argument and drastically reduces the boilerplate code in the callers.
All trivial callers converted over.

* [PATCH 03/39] proc: introduce proc_create_seq_private
From: Christoph Hellwig @ 2018-04-19 12:41 UTC (permalink / raw)
To: Andrew Morton, Alexander Viro
Cc: Alexey Dobriyan, Greg Kroah-Hartman, Jiri Slaby, Corey Minyard,
Alessandro Zummo, Alexandre Belloni, linux-acpi, drbd-dev,

linux-kernel
In-Reply-To: <20180419124140.9309-1-hch@lst.de>
Variant of proc_create_data that directly take a struct seq_operations
argument + a private state size and drastically reduces the boilerplate
code in the callers.
All trivial callers converted over.
Signed-off-by: Christoph Hellwig <hch@lst.de>

* [PATCH 04/39] proc: introduce proc_create_single{,_data}
From: Christoph Hellwig @ 2018-04-19 12:41 UTC (permalink / raw)
To: Andrew Morton, Alexander Viro
Cc: Alexey Dobriyan, Greg Kroah-Hartman, Jiri Slaby, Corey Minyard,
Alessandro Zummo, Alexandre Belloni, linux-acpi, drbd-dev,
linux-ide, netdev, linux-rtc, megaraidlinux.pdl, linux-scsi,
devel, linux-afs, linux-ext4, jfs-discussion, netfilter-devel,
linux-kernel
In-Reply-To: <20180419124140.9309-1-hch@lst.de>
Variants of proc_create{,_data} that directly take a seq_file show
callback and drastically reduces the boilerplate code in the callers.
All trivial callers converted over.

* [PATCH 12/39] net: move seq_file_single_net to <linux/seq_file_net.h>
From: Christoph Hellwig @ 2018-04-19 12:41 UTC (permalink / raw)
To: Andrew Morton, Alexander Viro
Cc: Alexey Dobriyan, Greg Kroah-Hartman, Jiri Slaby, Corey Minyard,
Alessandro Zummo, Alexandre Belloni, linux-acpi, drbd-dev,
linux-ide, netdev, linux-rtc, megaraidlinux.pdl, linux-scsi,

linux-kernel
In-Reply-To: <20180419124140.9309-1-hch@lst.de>
This helper deals with single_{open,release}_net internals and thus
belongs here.

* [PATCH 19/39] sg: simplify procfs code
From: Christoph Hellwig @ 2018-04-19 12:41 UTC (permalink / raw)
To: Andrew Morton, Alexander Viro
Cc: Alexey Dobriyan, Greg Kroah-Hartman, Jiri Slaby, Corey Minyard,

linux-kernel
In-Reply-To: <20180419124140.9309-1-hch@lst.de>
Use remove_proc_subtree to remove the whole subtree on cleanup, and
unwind the registration loop into individual calls. Switch to use
proc_create_seq where applicable.

* [PATCH 30/39] netfilter/xt_hashlimit: switch to proc_create_{seq,single}_data

In-Reply-To: <20180419124140.9309-1-hch@lst.de>
And use proc private data directly instead of doing a detour
through seq->private.

The driver proc file hasn't been writeable for a long time, so this is
just dead code.

Thanks for those details! This is an impressive change in performance
indeed.
I think I will just keep it simple for the documentation. I will add the
following for bpf_redirect_map():
When used to redirect packets to net devices, this helper
provides a high performance increase over **bpf_redirect**\ ().
This is due to various implementation details of the underlying
mechanisms, one of which is the fact that **bpf_redirect_map**\ ()
tries to send packet as a "bulk" to the device.
And also append the following to bpf_redirect():
The same effect can be attained with the more generic
**bpf_redirect_map**\ (), which requires specific maps
to be used but offers better performance.
Best,
Quentin

Perhaps... It was open-coded since at this point there are no other
users. That'll make this tidier though.

Since you mention bpf_perf_event_read() here, we should mention that
bpf_perf_event_read_value() is recommended over bpf_perf_event_read()
in general. The latter bpf_perf_event_read() has some ABI quirks where
error and counter value are used as a return code (which is obviously
wrong to do since ranges may overlap). bpf_perf_event_read_value()
fixed this but also provides more features at the same time over the
old interface.

* [PATCH net-next 0/2] qed* : Use trust mode to override forced MAC
From: Shahed Shaikh @ 2018-04-19 12:50 UTC (permalink / raw)
To: davem; +Cc: netdev, Ariel.Elior, Dept-EngEverestLinuxL2
Hi Dave,
This patchset adds a support to override forced MAC (MAC set by PF for a VF)
when trust mode is enabled using
#ip link set dev <pf> vf <vf id> trust on
First patch adds a real change to use .ndo_set_vf_trust to override forced MAC
and allow user to change VFs from VF interface itself.
Second patch takes care of a corner case, where MAC change from VF won't
take effect when VF interface is down, by introducing a new TLV
(a way to send message from VF to PF) to give a hint to PF to update
its bulletin board.
Please apply this series to net-next.
Thanks,
Shahed

qed* : use trust mode to allow VF to override forced MAC
qed* : Add new TLV to request PF to update MAC in bulletin board
