[Qemu-devel] [PATCH 01/46] qemu_ram_foreach_block: pass up error value, and down the ramblock name |
Date: |
Fri, 4 Jul 2014 18:41:12 +0100 |
From: "Dr. David Alan Gilbert" <address@hidden>
check the return value of the function it calls and error if it's none-0
Fixup qemu_rdma_init_one_block that is the only current caller,
and __qemu_rdma_add_block the only function it calls using it.
Pass the name of the ramblock to the function; helps in debugging.
Signed-off-by: Dr. David Alan Gilbert <address@hidden>
