For a few years now, we have been told that upcoming non-volatile memory (NVM)

we introduced above, we can actually relatively freely mix and match apps
and OSes, or develop against specific frameworks in specific versions on
any operating system.

Kernel prepatch 3.17-rc3

The 3.17 development cycle continues with the release of 3.17-rc3. "As expected, it is larger
than rc2, since people are clearly getting back from their Kernel Summit
