Remote machine's filesystem was scrambled when transferring large number of files

[zliucd]

Hi,

The remote machine's filesystem was scrambled when transferring a large number of small files. The Linux /home/<user> directory was completed removed during transfer, and the client's rsync reported an error(I forgot to take a snapshot). In addition, the Linux could not start with GUI.

Remote server: Centos 8.5 amd64, filesystem: XFS, disk: NVME SSD
Client: OSX Sonoma, rsync 2.6.9

Command: rsync -ah --progress <src> <dest>

It's not sure this is caused by kernel(file system) or rsync. Maybe this issue is hard to reproduce, and further investigation is appreciated. Let me know if I could provide more bug details.

LOSF（Lots of small files）transfer is a classical senario. I have tried rsync with 4k X 100,000,000 files' direcotry. It works well and its function of synchonisation.
