Hi,
Not sure if it's the kernel or the mount tool (more likely to be mount
tool? As switching back to v6.3 doesn't help), but 'atime' mount option
caused Btrfs/Ext4/Xfs to fail without any useful error messages:
# mkfs.ext4 test.img
# mount -o atime test.img /mnt/data/
mount: /mnt/data: not mount point or bad option.
dmesg(1) may have more information after failed mount system call.
# dmesg | tail -n 4

[ 168.742701] EXT4-fs (loop0): unmounting filesystem
3ed71bc6-d7d0-43d3-9f9a-7187133d83d4.
The same applies to XFS and Btrfs, none of the mount tool or dmesg shows
any clue on this.
For the btrfs part, the mount entrance (btrfs_mount()) returned no
error, thus it's pretty weird why the mount can still fail.
Is this a known problem?
Thanks,
Qu
