From f7f438589f4686758ee1de99c7723919a2b05d70 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 5 Jul 2023 15:01:21 -0400 Subject: kernfs: convert to ctime accessor functions In later patches, we're going to change how the inode's ctime field is used. Switch to using accessor functions instead of raw accesses of inode->i_ctime.
