[Cluster-devel] [DLM PATCH] DLM: Don't specify WQ_UNBOUND for the ast callback workqueue

2016-10-19 Thread Bob Peterson
Hi, 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. Signed-off-by: Bob Peterson
