From e00ee21dd3c9cd717fcc0feccf9c155e9d6ccdcb Mon Sep 17 00:00:00 2001 From: Yuanzheng Song Date: Thu, 28 Apr 2022 06:39:24 +0000 Subject: [PATCH] dma-buf: add the name field to the table header MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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.
