Felipe asked you to do the split since he believes that the notifier chain call for musb xceiv and the twl->phy notifier head init should be done in two separate patches. I agree with him since is better to separate bugfixs from new features for different reasons. For example if is found that a feature has to be reverted, then this won't revert a bugfix causing a regression. Also, it is easier to review and the bugfix patch can be cherry-picked by stable kernels. You said that to copy isolated patch/hunk from one mail to another is hassling so why do you want Felipe to do that? He like most most sub-system maintainers is very busy so if we want the kernel to scale we have to help them to make their live easier. So, I don't understand from where your anger comes for just the need to split your patch in two and send correct patches with git send-email so Felipe can apply easily with git am mbox or whatever worfklow he has. This is not the first time you contribute to the kernel so you know that the above patch s not only not in the correct format to be applied but also has a very offensive commit changelog that is not suitable for the kernel. Take a deep breath, grab a mug of coffee and then just split your patches and repost as v2, I'm sure you spent more time writing that angry email that what it would have taken to do it properly ;-) > -- > Pali Rohár > pali.rohar@gmail.com Best regards, Javier From mboxrd@z Thu Jan 1 00:00:00 1970 From: Javier Martinez Canillas Subject: Re: [PATCH 1/4] usb: musb: Call atomic_notifier_call_chain when status is changed Date: Wed, 18 Sep 2013 11:04:58 +0200 Message-ID: References: <1378630239-10006-1-git-send-email-pali.rohar@gmail.com> <201309172128.42514@pali> <20130918014942.GD19817@radagast> <201309181020.15245@pali> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: QUOTED-PRINTABLE Return-path: In-Reply-To: <201309181020.15245@pali> Sender: linux-kernel-owner@vger.kernel.org To: =?UTF-8?Q?Pali_Roh=C3=A1r?= Cc: Felipe Balbi , Tony Lindgren , Anton Vorontsov , Russell King , David Woodhouse , Greg Kroah-Hartman , freemangordon@abv.bg, Aaro Koskinen , Pavel Machek , "linux-omap@vger.kernel.org" , "linux-arm-kernel@lists.infradead.org" , Linux Kernel , linux-usb@vger.kernel.org List-Id: linux-omap@vger.kernel.org On Wed, Sep 18, 2013 at 10:20 AM, Pali Roh=C3=A1r wrote: > On Wednesday 18 September 2013 03:49:42 Felipe Balbi wrote: >> On Tue, Sep 17, 2013 at 09:28:42PM +0200, Pali Roh=C3=A1r wrote: >> > On Tuesday 17 September 2013 18:08:35 Felipe Balbi wrote: >> > > On Tue, Sep 17, 2013 at 06:05:15PM +0200, Pali Roh=C3=A1r wrote: >> > > > On Tuesday 17 September 2013 17:48:59 you wrote: >> > > > > On Sun, Sep 08, 2013 at 10:50:36AM +0200, Pali Roh=C3=A1r wr= ote: >> > > > > > More power supply drivers depends on vbus events and >> > > > > > without it they not working.

Felipe asked you to do the split since he believes that the notifier chain call for musb xceiv and the twl->phy notifier head init should be done in two separate patches. I agree with him since is better to separate bugfixs from new features for different reasons. For example if is found that a feature has to be reverted, then this won't revert a bugfix causing a regression. Also, it is easier to review and the bugfix patch can be cherry-picked by stable kernels. You said that to copy isolated patch/hunk from one mail to another is hassling so why do you want Felipe to do that? He like most most sub-system maintainers is very busy so if we want the kernel to scale we have to help them to make their live easier. So, I don't understand from where your anger comes for just the need to split your patch in two and send correct patches with git send-email so Felipe can apply easily with git am mbox or whatever worfklow he has. This is not the first time you contribute to the kernel so you know that the above patch s not only not in the correct format to be applied but also has a very offensive commit changelog that is not suitable for the kernel. Take a deep breath, grab a mug of coffee and then just split your patches and repost as v2, I'm sure you spent more time writing that angry email that what it would have taken to do it properly ;-) > -- > Pali Roh?r > pali.rohar at gmail.com Best regards, Javier
