[PATCH 1/2] padata: Do not mark padata_mt_helper() as __init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When building arm64 allmodconfig + ThinLTO with clang and a proposed
modpost update to account for -ffuncton-sections, the following warning
appears:

  WARNING: modpost: vmlinux.o: section mismatch in reference: padata_work_init (section: .text.padata_work_init) -> padata_mt_helper (section: .init.text)
  WARNING: modpost: vmlinux.o: section mismatch in reference: padata_work_init (section: .text.padata_work_init) -> padata_mt_helper (section: .init.text)

In both cases, an __init function calls padata_work_init(), which is not
marked __init, with padata_mt_helper(), another __init function, as a
work function argument.

padata_work_init() is called from non-init paths, otherwise it could be
marked __init to resolve the warning. Instead, remove __init from
padata_mt_helper() to resolve the warning.
