This stabilizes the forward-walkcursor, but does not prevent a new mark from being inserted before it.For example, an inotify watch re-added after IN_IGNORED sorts before theold, detached mark for the same group. The walk can miss the replacementand then detach the entire connector from the object.\nThe replacement is still on its group's marks_list and, for inotify, inthe watch IDR. The group mutex no longer protects the connector's objectfrom disappearing. An unprivileged fdinfo read racing the final detachcan consequently call igrab(NULL):\n  BUG: KASAN: null-ptr-deref in igrab+0x24/0x100  Write of size 4 at addr 0000000000000148  Call Trace:   igrab+0x24/0x100   inotify_show_fdinfo+0x1dc/0x5e0   seq_show+0x397/0x690\nSet a DESTROYING flag under conn->lock before starting the walk, andreject new marks on that connector with -ENOENT. The existing add-markerror paths undo the temporary group-list entry and the backend's watchallocation. Do not wait for teardown while holding the group mutex,which the destroyer needs. Once the old connector is detached, an addcan install a fresh connector as before.\nThis closes the insertion race for all object types using the commonconnector teardown, without changing the mark reference or SRCU
