See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-fsdevel@vger.kernel.org Hi all, this series adds support to boot off arbitrary non-blockdevice root file systems, based off an earlier patch from Vivek. Chances since v1: - don't try to mount every registered file system if none is specified - fix various null pointer dereferences when certain kernel paramters are not set - general refactoring.
