quota/marker: use smaller stacksize in synctask for marker updation
Default stacksize that synctask uses is 2M. For marker we set it to 16k Also move market xlator close to io-threads to have smaller stack Change-Id: I8730132a6365cc9e242a3564a1e615d94ef2c651 BUG: 1207735 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11499 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
