Author: pfg Date: Mon Jan 8 15:41:48 2018 New Revision: 327697 URL: https://svnweb.freebsd.org/changeset/base/327697 Log: malloc(9): drop the __result_use_check attribute for the kernel allocator. The __result_use_check attribute was brought to the kernel malloc in r281203 for consistency with the userland malloc. For the case of the M_WAITOK flag, the kernel malloc(), realloc(), and reallocf() cannot return NULL so in that case the __result_use_check attribute makes no sense. We don't have any way of conditionalizing such attributes so just drop it.
