mmc: queue: append partition subname to queue thread name
For example, an eMMC with 2 boot partitions will have 3 threads. The names change from: 40 ? 00:00:00 mmcqd/0 41 ? 00:00:00 mmcqd/0 42 ? 00:00:00 mmcqd/0 to: 40 ? 00:00:00 mmcqd/0 41 ? 00:00:00 mmcqd/0boot0 42 ? 00:00:00 mmcqd/0boot1 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Andrei Warkentin <andreiw@motorola.com> Signed-off-by: Chris Ball <cjb@laptop.org>
