+Subject: [PATCH 1/6] net: inform NETDEV_CHANGE callbacks which flags were
+ changed
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In certain cases (like the follow up commit to arp.c) will need to
+check which flags actually changed to avoid excessive work.
+
+Ben Hutchings nicely worded why to put these transient flags to
+struct net_device for the time being:
+> It's inelegant to put transient data associated with an event in a
+> persistent data structure.  On the other hand, having every user cache
+> the old state is pretty awful as well.
+>
+> Really, netdev notifiers should be changed to accept a structure that
+> encapsulates the changes rather than just a pointer to the net_device.
+> But making such a change would be an enormous pain and error-prone
+> because notifier functions aren't type-safe.
+>
+> As an interim solution, I think either the general flags_changed or
+> old_flags would be preferable to defining extra transient flags.

+ events
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 05ab86c5 (xfrm4: Invalidate all ipv4 routes on
+IPsec pmtu events). Flushing all cached entries is not needed.
+
+Instead, invalidate only the related next hop dsts to recheck for
+the added next hop exception where needed. This also fixes a subtle
+race due to bumping generation id's before updating the pmtu.

+Subject: [PATCH 5/6] ipv4: use separate genid for next hop exceptions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 13d82bf5 (ipv4: Fix flushing of cached routing informations)
+added the support to flush learned pmtu information.
+
+However, using rt_genid is quite heavy as it is bumped on route
+add/change and multicast events amongst other places. These can
+happen quote often, especially if using dynamic routing protocols.
+
+While this is ok with routes (as they are just recreated locally),
+the pmtu information is learned from remote systems and the icmp
+notification can come with long delays. It is worthy to have separate
+genid to avoid excessive pmtu resets.

 assmued that "locally destined, and routed packets, never trigger

 It also seems that we really need to have the PMTU information always

+for netfilter TCPMSS clamp-to-pmtu feature to work properly.
 
 So for the time being, cache separate copies of input routes for
 each next hop exception.

-I had ideas to make optimizations where pmtu information would not
-be needed. This includes:
-- Target devices with IFF_XMIT_DST_RELEASE set (practically all devices
-  except tunnels). If skb_dst() is early freed the target device cannot
-  generate PMTU events
-- Add flag for input route generation if pmtu info is needed for
-  fragmentation. Basically a flag saying if DF bit was set in ip_hdr.
-
-However, TCPMSS clamp-to-pmtu prevents both optimizations.
-
-I'm not yet all familiar with the recent changes in routing caching,
-so there might be caveats that I missed. Basic testing shows this fixes
-the fragmentation issues I'm seeing, and I have not yet found any ill
-side effects either.

-The output route check was introduced with git commit 261663b0
-(ipv4: Don't use the cached pmtu informations for input routes)
-during times when we cached the pmtu informations on the
-inetpeer. Now the pmtu informations are back in the routes,
-so this check is obsolete. It also had some unwanted side effects,

-Subject: [PATCH] leds: leds-gpio: reserve gpio before using it
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reverts commit a99d76f (leds: leds-gpio: use gpio_request_one)
-and commit 2d7c22f (leds: leds-gpio: set devm_gpio_request_one()
-flags param correctly) which was a fix of the first one.
-
-The conversion to devm_gpio_request in commit e3b1d44c (leds:
-leds-gpio: use devm_gpio_request_one) is not reverted.
-
-The problem is that gpio_cansleep() and gpio_get_value_cansleep()
-calls can crash if the gpio is not first reserved. Incidentally this
-same bug existed earlier and was fixed similarly in commit d95cbe61
-(leds: Fix potential leds-gpio oops). But the OOPS is real. It happens
-when GPIOs are provided by module which is not yet loaded.
-
-So this fixes the following BUG during my ALIX boot (3.9.2-vanilla):
-

-which reflect the change. But I agree that the clearing out bit was
-misplaced. This is especially true as it seems NETDEV_CHANGE can be
-notified from another place too.
-
-I've updated the if.h comment to state that the bit is valid only during
-NETDEV_CHANGE notifier. And __dev_notify_flags is updated to always clear
-the bit after notifiers are done.
