I attempted to reproduce the issue using the script provided in this
link: 
https://download.01.org/0day-ci/archive/20240903/202409031358.2c34ad37-oliver.sang@intel.com/repro-script.
but I discovered that it might not be related to my patch. After I
reverted my own fsmap-related patches locally and ran the test case
using this script, it still failed.

I'm not sure if it's due to an issue with my own environment or if there
are other factors I haven't considered.

However, I still found the current problems of fsmap, and I am not sure
whether it is related to these two.[1][2]
