  "message": "9pfs: handle walk of \"..\" in the root directory\n\nThe 9P spec at http://man.cat-v.org/plan_9/5/intro says:\n\nAll directories must support walks to the directory .. (dot-dot) meaning\nparent directory, although by convention directories contain no explicit\nentry for .. or . (dot).  The parent of the root directory of a server\u0027s\ntree is itself.\n\nThis means that a client cannot walk further than the root directory\nexported by the server. In other words, if the client wants to walk\n\"/..\" or \"/foo/../..\", the server should answer like the request was\nto walk \"/\".\n\nThis patch just does that:\n- we cache the QID of the root directory at attach time\n- during the walk we compare the QID of each path component with the root\n  QID to detect if we\u0027re in a \"/..\" situation\n- if so, we skip the current component and go to the next one\n\nSigned-off-by: Greg Kurz \u003cgroug@kaod.org\u003e\nReviewed-by: Eric Blake \u003ceblake@redhat.com\u003e\nSigned-off-by: Peter Maydell \u003cpeter.maydell@linaro.org\u003e\n",
