[Qemu-devel] [PATCH 00/10] FORTIFY_SOURCE followup

[Juan Quintela]

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.
