Qu, Thank you very much for detailed response.
I would like to understand something, on VFS, it is guaranteed that in
a given filesystem, only 1 inode number will be used, it is unique.
In btrfs, you say the inode uniqueness is per volume, each volume has
its own inode space, How is it possible ?

Qu,
Given inode, i get the fsid via: inode->i_sb->s_dev;
this return dev_t and not u8/u16

Hello,
since around two or three years i'm using btrfs for incremental VM backups.
some data:
- volume size 60TB
- around 2000 subvolumes
- each differential backup stacks on top of a subvolume
- compress-force=zstd
- space_cache=v2
- no quote / qgroup
this works fine since Kernel 4.14 except th

That's just a device number.
Not really useful in btrfs, since btrfs is a multi-device filesystem.

Thanks, chattr +C is that's what I am currently using.
Also you already answered my next question, why it is not possible to set +C

I want to exclude my ~/.cache directory from snapshots. The obvious
way to do this is to mount a btrfs subvolume at that location.
However, I also want the ~/.cache directory to be nodatacow. Since the
parent volume is COW, I believe it isn't possible to mount the
subvolume with different mount op

Hi David,
Would you please queue this patch to devel branch?
This is a small enough, but quite important fix when handling dump tree
output.
Thanks,
