Union mount provides the filesytem namespace unification feature. Unlike the traditional mounts which hide the contents of the mount point, the union mount presents the merged view of the mount point and the mounted filesytem. These patches were originally developed for 2.6.11 by Jan Blunck and lately we have been working together in taking this forward. The current patchset applies against 2.6.21-rc6-mm1. The code is in a highly experimental stage at the moment and the intention of posting this now is to get some initial feedback about the design and the future directions about how this should be taken forward. You can find more details about union mount in the documentation included in the patchset. Kindly review and let us know your comments. Regards, Bharata.
