commit e6db5eb9ec7ba9edfc564fd5ade5fb40df9acebb Author: Colin Percival <[email protected]> AuthorDate: 2021-12-20 15:17:25 +0000 Commit: Colin Percival <[email protected]> CommitDate: 2021-12-29 20:41:08 +0000 vfs_mountroot: Skip 'Root mount waiting' < 1 s While the message is technically correct, it's not particularly helpful in the case where we're only waiting a few ms; this case occurs frequently on EC2 arm64 instances with CAM initialization racing to release its root hold before vfs_mountroot reaches this point. Only print the message if we end up waiting for more than one second.
