closed[PATCH] kernel -- Remove unused hogticks global from kern_synch.c
0%
Description
hogticks was a global definition used in kern_synch.c:should_yield().
A thread that had remained running for more than hogticks would
return true for should_yield(). DragonFly has not used this global
for a long time.
