From: Greg KH To: Linus Torvalds , Andrew Morton Cc: linux-kernel@vger.kernel.org Subject: [GIT PATCH] Remove devfs from 2.6.17 They are the same "delete devfs" patches that I submitted for 2.6.12 and 2.6.13 and 2.6.14 and 2.6.15 and 2.6.16. It rips out all of devfs from the kernel and ends up saving a lot of space. Since 2.6.13 came out, I have seen no complaints about the fact that devfs was not able to be enabled anymore, and in fact, a lot of different subsystems have already been deleting devfs support for a while now, with apparently no complaints (due to the lack of users.) This patchset has also been in the -mm tree, with no complaints or issues for the past few months. It's also been almost a full year past the date when we said we would delete devfs from the kernel tree in the file, Documentation/feature-removal-schedule.txt, almost two years since we publicly announced to the world that devfs would be removed from the kernel tree. So, I think people have had plenty of advance notice that this was going to happen by now :) Please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/devfs-2.6.git/ or if master.kernel.org hasn't synced up yet: master.kernel.org:/pub/scm/linux/kernel/git/gregkh/devfs-2.6.git/ I've posted all of these patches before, but if people really want to look at them, they can be found at: http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-05-devfs/ Also, if people _really_ are in love with the idea of an in-kernel devfs, I have posted a patch that does this in about 300 lines of code, called ndevfs. It is available in the archives if anyone wants to use that instead (it is quite easy to maintain that patch outside of the kernel tree, due to it only needing 3 hooks into the main kernel tree.)
