hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

From: Roberto Sassu <roberto.sassu at huawei.com> One of the major goals of LSM stacking is to run multiple LSMs side by side without interfering with each other. The ultimate decision will depend on individual LSM decision. Several changes need to be made to the LSM infrastructure to be able to support that.

This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers. Changes since previous version: - Fix documentation error that got noticed by the kbuild bot in "drm/dp_mst: Pass entire connector to

One patch was reshuffled and two ACKs I missed to add were added. The rebase did not require any modifications to patches. Details about virtio-mem can be found in the cover letter of v2 [2]. A
