From 823d1bc1082970fc02f8172859c789933ed84bc5 Mon Sep 17 00:00:00 2001 From: Emilio López Date: Mon, 19 Sep 2016 01:21:20 -0300 Subject: dma-buf/sync_file: fix documentation error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ioctl name and description on the documentation block don't match the ioctl being defined. This was probably overlooked while renaming the ioctls during the sync file destaging. This patch provides a more accurate description of what the ioctl actually does.
