[Qemu-trivial] [PATCH 0/3] os-posix: improve the error message printing

[arei.gonglei]

From: Gonglei <address@hidden>

The patches mainly improve the error message printing.
And adjust coding style of os-posix.c.

Daemonize the QEMU process after initialization, QEMU will not detach from
standard IO until it is ready to receive connections on any of its devices.
So, using fprintf print error.

Gonglei (3):
  os-posix: change tab to space avoid violating coding style
  os-posix: remove confused errno
  os-posix: report error message when lock file failed
