The article linked at the top is nonsense. It references kernel fixes from three years ago. Then, says we need AzureLinux 2.0 with kernel version 5.15.159 to pick them up. 🤨
There is a known SMB client regression that is present in 5.15.153. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.15.158&id=929ba00702cfba77fbb3fbc88d9a0f6e2af2f6b6
Could this regression explain the behavior seen here? If so, it's fixed in 5.15.158.

this is fixed in 5.15.160.1-1.cm2 which was released a week ago or so. thanks for the link to the regression bug . later i realized that's the case too.
Describe the bug kernel SMB client does not automatically update IP address of the cifs mount after DNS update.
This is a known issue in some early versions of Linux kernel and should have been fixed. However i can still reproduce this issue on latest AzureLinux running 5.15+ kernel.
To Reproduce Steps to reproduce the behavior:
root [ /home/azureuser ]# uname -r 5.15.153.1-2.cm2
root [ /home/azureuser ]# rpm -qa | grep keyutils keyutils-1.6.3-1.cm2.x86_64
