Revision 67bf47452ea00edd90e796054229b651e64b82c1 authored by Masahiro Yamada on 17 July 2019, 06:29:13 UTC, committed by Masahiro Yamada on 20 July 2019, 02:19:29 UTC
- Some headers graduated from the blacklist - hyperv_timer.h joined the header-test when CONFIG_X86=y - nf_tables*.h joined the header-test when CONFIG_NF_TABLES is enabled. - The entry for nf_tables_offload.h was added to fix build error for the combination of CONFIG_NF_TABLES=n and CONFIG_KERNEL_HEADER_TEST=y. - The entry for iomap.h was added because this header is supposed to be included only when CONFIG_BLOCK=y Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
