Hi Hemanth,

Thanks for the new version. It looks better, but we still have at least
one ptest issue:

Failed ptests:
{'glib-2.0': ['glib/gdatetime.test']}

https://autobuilder.yoctoproject.org/valkyrie/#/builders/56/builds/1216
https://autobuilder.yoctoproject.org/valkyrie/#/builders/61/builds/3225
https://autobuilder.yoctoproject.org/valkyrie/#/builders/73/builds/3252

Test logs can be found here:

https://valkyrie.yocto.io/pub/non-release/20260311-60/testresults/qemuriscv64-ptest/core-image-ptest-glib-2.0/
https://valkyrie.yocto.io/pub/non-release/20260311-60/testresults/qemuarm64-ptest/core-image-ptest-glib-2.0/
https://valkyrie.yocto.io/pub/non-release/20260311-60/testresults/qemux86-64-ptest/core-image-ptest-glib-2.0/

We also have this busybox ptest failure, only on arm64. I suspect it is
related to this series, but I will launch a build to confirm.

Failed ptests:
{'busybox': ['printf_understands_%s_\'"x\'_"\'y"_"\'zTAIL"',
             'printf_handles_positive_numbers_for_%f']}

Thanks,
Mathieu
