From e924381bae58ca828c9691b9d4d772a20a91c717 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Fri, 11 May 2012 16:23:06 +0200 Subject: Command throttling breaking HWM algorithms -- fixed. When HWM was set to small value it may have happened that command indicating that pipe is ready for writing wasn't processed because of command throttling.
