AFAIK, per-subvolume *atime mounts should already be working. The *atime mount options are filesystem-generic (aka Linux vfs level), and while I my own use-case doesn't involve subvolumes, the wiki says they should be working (wrapped link I'm not bothering to jump thru the hoops to properly unwrap): https://btrfs.wiki.kernel.org/index.php/FAQ #Can_I_mount_subvolumes_with_different_mount_options.3F So while personally untested, per-subvolume *atime mount options /should/ "just work". Meanwhile, I've simply grown to hate atime as an inefficient and mostly useless drain on resources, so I pretty much just noatime everything, the reason I decided to bother patching my kernel to make that the default, instead of having yet another option I use everywhere anyway, clogging up the options field in my fstab. -- Duncan - List replies preferred.
