wifi: cfg80211: undo netns switch if renaming the wiphy fails<\/p>\n
Once all the interfaces have been moved, cfg80211_switch_netns()
\nmoves the wiphy itself by setting its network namespace and then
\nrenaming it, which makes sysfs move it. The rename can fail (but
\nonly on allocation failures), leaving things mixed up and hitting
\nthe warning there.<\/p>\n
Ignoring it isn’t great, undo the move and let the change fail
\nin this case. If undo fails then WARN, then things would again
\nbe stuck in two different network namespaces.<\/p>\n","protected":false},"excerpt":{"rendered":"
