From 808b88915b7332c3ba51559012fca69cdf403dc5 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Tue, 17 May 2022 16:50:30 +0200 Subject: [PATCH] btrfs: send: add OTIME as utimes attribute for proto 2+ by default When send v1 was introduced the otime (inode creation time) was not available, however the attribute in btrfs send protocol exists. Though it would be possible to add it for v1 too as the attribute would be ignored by v1 receive, let's not change the layout of v1 and only add that to v2+. The otime cannot be changed and is only informative.
