From 18f57327e0c2c669034e1fff1260877fd70c3038 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Thu, 8 Feb 2018 14:27:59 -0800 Subject: Linux 4.16 compat: inode_set_iversion() A new interface was added to manipulate the version field of an inode. Add a inode_set_iversion() wrapper for older kernels and use the new interface when available. The i_version field was dropped from the trace point due to the switch to an atomic64_t i_version type.
