From 6c01aa13894fa0049ea8c96c271318ca353a77f1 Mon Sep 17 00:00:00 2001 From: Yuanzheng Song Date: Thu, 28 Apr 2022 06:39:24 +0000 Subject: dma-buf: add the name field to the table header MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 'cat /sys/kernel/debug/dma_buf/bufinfo' will print the Dma-buf Objects' information when the CONFIG_DEBUG_FS=y. However, the printed table header information does not contain the name field. So we need to add the name field to the table header and use the '' to replace the empty buf_obj->name.
