From 330694a50f5b80e983136237c10516810fb427a9 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Sun, 6 Nov 2011 18:37:23 +0100 Subject: [PATCH] target: Improve system responsivity during I/O While testing ib_srpt I noticed that the target system became rather unresponsive during intensive I/O. The patch below made my target system responsive again during I/O without decreasing performance.
