Description of problem:
If I create a symbolic link to a file on Glusterfs that has a long enough filepath it results in a link that does not point anywhere.

The exact command to reproduce the issue:

echo test > /mnt/glustervol1//symlink-test/0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000/test_target
ln -s /mnt/glustervol1//symlink-test/0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000/test_target /mnt/glustervol1//symlink-test/0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000/test_link

Expected results:

No errors or warnings on the server nodes.
- Is there any crash ? Provide the backtrace and coredump
No.

Additional info:
All the glusterfs servers and clients are virtual machines within an Openstack deployment. The glusterfs bricks are created on Openstack Volumes. All the clients mount glusterfs with option noatime. On a NFS mount (not Glusterfs) the above command produces a valid link.

- The operating system / glusterfs version:
Rocky Linux 9.0 / glusterfs 11.1

Can you run the command with strace (strace -Tttf ) and share the data with brick logs?

Here is the strace for the link creation:

And here for ls:

It seems there is no issue with link creation but lookup operation is failing. I have tested the same in my environment , it is working fine. It is calling statx not stat, in previous version it call stat. I have to test it on latest rhel version then can update on the same.
