This is v4 of a proposed patch set for fixing file ID collisions with 9pfs.
v3->v4: * Rebased to latest git master head. * Splitted Antonios' patch set to its original 4 individual patches. (was merged previously as only 1 patch). * Addressed discussed issues directly on Antonios' patches (was a separate patch before). * Added virtfs command line option "remap_inodes": Unless this option is not enabled, no inode remapping is performed at all, the user just gets an error message when trying to use more than 1 device per export. * Dropped persistency feature of QIDs beyond reboots. * Dropped disputed "vii" feature. Greg, please check if I am doing anything superfluous in patch 3 regarding the new command line parameter "remap_inodes". Daniel, I also have a libvirt patch for this new "remap_inodes" command line parameter, but I guess I wait for this qemu patch set to get through.
