I released umockdev 0.2.6. Most importantly, this now fully works on ARM platforms, as we want to use it to write tests for/on the Ubuntu phone. I tested it on my Nexus 7, and the tests also succeed on the ARM Ubuntu builder (which are Panda boards). Fixing this revealed some interesting issues in recorded ioctl traces (as they are platform specific in some cases due to different word length) as well as kernel bugs in the Tegra drivers.
This version also fixes compatibility with older automake versions again, so that the daily builds for raring should work again.
I also have a new gvfs test case ready to commit which uses umockdev (if available) to test functionality of the gphoto backend. But that needs the new UMockdevTestbed.clear()
API in 0.2.6, so I was holding that back. I will land it soon in upstream git now.
