Hi This series make: - all block *_create() functions return -errno instead of -1 - this makes that we can end writting errno/error at bdrv_create() callers (qemu-img) - once there found a double free problem in the error handling of vmdk, fixed it. - slirp: also check that system() was able to fork (amit noticed it) - daemonize: if we are unable to write into the pipe, print a message and exit. We can't really recover from that error (amit noticed it).
Please review and apply. Later, Juan.
