Subject: [patch] task_prio() fix
Date: 20 Feb 2003 18:42:40 -0500 [thread overview]
Message-ID: <1045784559.781.26.camel@phantasy> (raw)
Looks like task_prio() should do:
int task_prio(task_t *p)
{
return p->prio - MAX_RT_PRIO;
}
Instead of subtracting MAX_USER_RT_PRIO, since the maximum _user_ value
has nothing to do with the maximum that may be stored. The effect is if
MAX_RT_PRIO != MAX_USER_RT_PRIO, then all priorities are skewed by
(MAX_RT_PRIO - MAX_USER_RT_PRIO).
Ingo, this looks trivial to me... but I swear it _used_ to work and this
function has always been like this. Comments?
Patch is against 2.5.62.
