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.
