Re: Re: [PATCH] lkdtm/core: fix resource leaks on module init error path

[Jiangshan Yi]

Hi,

Thanks for the build test report and for catching these section mismatch
warnings:

> > > WARNING: modpost: drivers/misc/lkdtm/lkdtm: section mismatch in reference: lkdtm_module_init+0x221 (section: .init.text) -> lkdtm_heap_exit (section: .exit.text)
> > > WARNING: modpost: drivers/misc/lkdtm/lkdtm: section mismatch in reference: lkdtm_module_init+0x226 (section: .init.text) -> lkdtm_usercopy_exit (section: .exit.text)

These warnings have already been addressed in the v2 of this patch,
posted at:

https://lore.kernel.org/all/20260730154911.3164527-1-yijiangshan@xxxxxxxxxx/

In v2, the error-handling path in lkdtm_module_init() no longer
references the .exit.text cleanup helpers (lkdtm_heap_exit,
lkdtm_usercopy_exit), which resolves the section mismatch reported
by modpost.

Since the fix is part of a new version of the same patch rather than a
separate commit, I haven't added the Reported-by / Closes tags to
that version. However, your report was very helpful in confirming the
issue — thank you again for the testing.

Best regards,
Jiangshan Yi
