Btrfs specific tests is missing

[oech3]

I think there are no Btrfs specifc tests at here something like

• reflink
• cp,mv,install compressed file to non-Btrfs cp, mv, install: Can't move a file on compressed Btrfs to tmpfs uutils/coreutils#9771
• rm subvolumes on newer kernel

Hi, I’m a beginner contributor and interested in working on this. Is this suitable for a first contribution?

@charulata871 cool. Note cp --debug may be useful to know if reflinking was attempted/supported.
There are existing tests that create loopback mounts, which hopefully suffice as a template for this. thanks!

There are existing tests that create loopback mounts,

cp-mv-enotsup-xattr.sh? ext* does not have compression.

Sorry, I meant existing tests that can be used as a template

I see. Thankyou.

@charulata871 any progress?

Hi @oech3, thanks for checking in.

I’ve been going through the existing loopback-mount tests to understand the pattern and using them as a template, as suggested. I’m still getting familiar with this part of the codebase, but I’m making progress and plan to start implementing the changes next.

I’ll share an update or draft PR once I have something ready. Thanks for your patience!

Ok. Thankyou.
