I see there are periodic trivial pull requests. I assume there are maintainers that collect these up into trees?

Once your patch is reviewed it should be merged by a maintainer. > What's the typical lag for trivial patches getting in? I see there are > periodic trivial pull requests. I assume there are maintainers that > collect these up into trees? Contributors send patches to qemu-devel. After the patches are reviewed they are merged either directly into qemu.git or into a subsystem tree by a maintainer. Subsystem maintainers send pull requests to flush their patch queue when they feel it is appropriate. For example, Kevin and I send a weekly block layer pull request that usually contains 5-15 patches. Expect 1.5 weeks to get the average patch reviewed and merged into qemu.git. If you're lucky they can be merged in a day. If you're unlucky you may have to ping the list to move the process along. Stefan
