Subject: Revert "pkt_sched: Add BH protection for qdisc_stab_lock."
X-Git-Tag: v2.6.27-rc4~39^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f3b9605d744df537dee10fd06630f35a62b343ec;p=linux-2.6

Revert "pkt_sched: Add BH protection for qdisc_stab_lock."

This reverts commit 1cfa26661a85549063e369e2b40275eeaa7b923c.

qdisc_destroy() runs fully under RTNL again and not from softint any
longer, so this change is no longer needed.
