Subject: [NET_SCHED]: Show timer resolution instead of clock resolution in /proc/net/psched
X-Git-Tag: v2.6.24-rc1~1454^2~31
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3c0cfc135829b98f7a4894938652f9ef78e24237;p=linux-2.6

[NET_SCHED]: Show timer resolution instead of clock resolution in /proc/net/psched

The fourth parameter of /proc/net/psched is supposed to show the timer
resultion and is used by HTB userspace to calculate the necessary
burst rate. Currently we show the clock resolution, which results in a
too low burst rate when the two differ.
