From 078cd8279e659989b103359bb22373cc79445bde Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Wed, 14 Sep 2016 07:48:04 -0700 Subject: fs: Replace CURRENT_TIME with current_time() for inode timestamps CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_time() instead. CURRENT_TIME is also not y2038 safe. This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. As part of the effort current_time() will be extended to do range checks. Hence, it is necessary for all file system timestamps to use current_time(). Also, current_time() will be transitioned along with vfs to be y2038 safe. Note that whenever a single call to current_time() is used to change timestamps in different inodes, it is because they share the same time granularity.
