From aa9f1012858bc7f44368f1e4453c989d873b0860 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 19 Oct 2016 11:34:54 -0400 Subject: dlm: don't specify WQ_UNBOUND for the ast callback workqueue This patch removes the WQ_UNBOUND flag (which implies WQ_HIGHPRI) from the DLM's ast work queue, in favor of just WQ_HIGHPRI. This has been shown to cause a 19 percent performance increase for simultaneous inode creates on GFS2 with fs_mark.
