Re: [libvirt] [PATCH] build: trivial fix error: implicit declaration of function 'malloc'

mask = CPU_ALLOC(numcpus); On glibc this is defined to a function _sched_cpualloc(), hence we don't see a warning. If your headers are defining this in terms of malloc(), then IMHO, the sched.h should be including stdlib.h on our behalf. IOW, I think this is a bug in the c library headers That all said, I'm not against adding this workaround in libvirt, provided the c library bug is reported upstream.
