is already out, lets do (as part of testing our theories out), a follow
up patch to sync up with v3.15. And finally, I think we need, in order
to keep this pain point down, sync per kernel release.
Ok, I had prepared a v5, posting it soon.
I try to do also to prepare a seperate sync with v3.15 patch, but give
me some time ... also I found a bug in current v3.16-rc1 kernel, using
ubi fastmap, see:
"UBI: fix rb_tree node comparison in add_map commit buggy?"
http://lists.infradead.org/pipermail/linux-mtd/2014-June/054348.html
So current v3.16-rc1 kernel could not attach a ubi volume using
ubi fastmap and created with a kernel not having commit
604b592e6fd3c98f21435e1181ba7723ffc24715 applied ... which is
the case for v3.14 ... with my fixup, a v3.16-rc1 kernel could
again attach a v3.14 kernel or U-Boot (with my v3.14 sync patches
applied) created ubi volume ...
Maybe we wait with the sync, until this is sorted out?
Yes, that's fine. Perhaps we'll end up with a sync to v3.14 series, a
v3.15 on top of it, and then backporting your bugfix patch(es) on top of
that.
Ok, so let us bring in the v3.14 sync in the next merge window. I try
to do some more tests with it ...
I did a fast sync with v3.15, compiled for arm, mips and powerpc
but I have to test this, and this will takes some time, I currently
not have ...
I did the sync in the following way:
- checked out in the linux tree the commit with which the U-Boot
sync was done.
- copy all linux mtd,ubi and ubifs files to the U-Boot mtd,ubi,ubifs
code
-> git diff will shows all U-Boot specific changes
-> save this patch
- now in the linux tree checked out the new commit I wanted to sync
U-Boot with
- copy all linux mtd,ubi and ubifs files from the new linux commit
to the U-Boot mtd,ubi,ubifs code
- committed this for documentation only
- apply the u-boot specific changes patch now
- fixed small errors
This worked with some small correction very fast ...
ToDo:
- test
- commit and send to ML
To sync us with each kernel release would be a good idea, but the
problem would be, to find time for it ...
Yes, but I think if we do it more regularly it will be better for us and
take less time.
Definitely.
bye,
Heiko
