Maybe, you are going to add the stable tag for next stable?
Thanks.
Yes, this definitely must be in next stable 3.4.x , but first I'll wait
for confirmation.
Guys, who can reproduce this, please check patch "radix-tree: fix
contiguous iterator"
from my previous mail in this thread.
radix-tree: fix contiguous iterator
From: Konstantin Khlebnikov<khlebnikov@xxxxxxxxxx>
This patch fixes bug in macro radix_tree_for_each_contig().
If radix_tree_next_slot() sees NULL in next slot it returns NULL, but
following
radix_tree_next_chunk() switches iterating into next chunk. As result
iterating
becomes non-contiguous and breaks vfs "splice" and all its users.
I patched on to off v3.4 and Firefox an Thunderbird do not segfault
anymore. The do not start either. This was de feature on my 'production'
server I could not reproduce on my test server. Maybe it has something
to with the different type of nic's.
For the second attempt I branched of at 0fc9d1040313047edf6a39fd and
applied your patch on top of it. Firefox an Thunderbird where back
again. So your patch works.
Now I need some git-instructions. Apparently something else is broken. I
branched of with:
git branch debug 0fc9d1040313047edf6a3
git checkout debug
applied the patch.
git commit -a (got commit 5c09c685ba2d36c3b905220d43ad1b47354e456eed back)
Now I want all commits in my master branch up until ref v3.4 added to my
debug branch so I can bisect between 5c09 and v3.4
