Hi there, i've been trying to patch the kernel to try and get it in top shape... but i discovered a few difficulties... my post talks about unionfs, but i'm really using it as an example. Every file referenced in this post are the ones found on the kernel.org site below: http://kernel.org/pub/linux/kernel/v2.6/ And unionfs patches are found on this page: http://www.filesystems.org/project-unionfs.html First, i tried with the 2.6.29 series and at the time of trying (and of writing this) the subminor version was up to 6 (2.6.29.6). Second, i want to add unionfs support to the vanilla sources, for kernel 2.6.29. The available patch for unionfs is 2.5.2 for kernel 2.6.29.4. Ok, now here's what i thought i had to do: on top of: linux-2.6.29.tar.bz2 1) patch with: patch-2.6.29.1.bz2 2) patch with: patch-2.6.29.2.bz2 3) patch with: patch-2.6.29.3.bz2 4) patch with: patch-2.6.29.4.bz2 5) patch with: unionfs-2.5.2_for_2.6.29.4.diff.gz 6) patch with: patch-2.6.29.5.bz2 7) patch with: patch-2.6.29.6.bz2 It made sense to me that they were all differential patches, but it appears they are cummulative since 2.6.29 (ie to get 2.6.29.6, you just use the 2.6.29.6 patch straight)... so during my trial, patch said some stuff is already patched, and the more i go down this list of patch the longer the 'already patched' messages. I guess the correct way would have been to 1) just patch with 2.6.29.4 straight, then 2) unionfs then 3) what? a) Make patch of the patch-2.6.29.6.bz2 from patch-2.6.29.4.bz2, and patch with this? (sounds hacky but fast) b) Or should i copy/snapshot the kernel sources when it is 2.6.29.4, then apply the other kernel patches up to 2.6.29.6, finally make my own patch from 26.29.4 to 2.6.29.6, then using the 2.6.29.4 patched source snapshot, patch with unionfs and then my 29.4_to_29.6 patch? (this one sounds safer but more trouble) c) At last, could git be of any help on this? I'm looking to work only with stable code... I'm asking because i feel there must be a "better practice" for this kind of manipulation... and well, it's a good thing i was just playing with unionfs and not a few more experimental drivers all at the same time!
