From a9185b41a4f84971b930c519f0c63bd450c4810d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 5 Mar 2010 09:21:37 +0100 Subject: pass writeback_control to ->write_inode This gives the filesystem more information about the writeback that is happening. Trond requested this for the NFS unstable write handling, and other filesystems might benefit from this too by beeing able to distinguish between the different callers in more detail.
