[Qemu-devel] [PULL 01/14] file_ram_alloc: propagate error to caller instead of terminating QEMU

[Paolo Bonzini]

From: Igor Mammedov <address@hidden>

QEMU shouldn't exits from file_ram_alloc() if -mem-prealloc option is specified
and "object_add memory-backend-file,..." fails allocation during memory hotplug.

Propagate error to a caller and let it decide what to do with allocation 
failure.
That leaves QEMU alive if it can't create backend during hotplug time and
kills QEMU at startup time if backends or initial memory were misconfigured/
too large.
