Greetings,

FYI, this debug patch discloses an old-but-still-active bug in

fixed by: bdca1fd9a6df ("fakelb: fix schedule while atomic").

Some more context. Looking at your config and script file names they suggest this is tested with 4.8.0-rc4. Fengguang, is that correct?

The fix from above is in 4.8.0-rc7
git describe bdca1fd9a6df
v4.8-rc6-1377-gbdca1fd

It should be send to stable. Stefan can you do that please?

The latest stable kernel is 4.10.1 and the latest longterm stable is 4.9.13. Both of them should have this fix already.

If there is a desire I could try sending it for the older longterm stable tree 4.4.x. Not sure if this is really worth the effort. Comments?
