[Qemu-devel] [PATCH 0/9] QMP/HMP: add error reason to open failures

[Luiz Capitulino <lcapitulino@redhat.com>]

Today I was surprised to find out that we still have old users of QERR_OPEN_FILE_FAILED that print errors like:

(qemu) dump-guest-memory -p /lkmads/foo
Could not open '/lkmads/foo'
(qemu)

This series converts all those users to a new helper called error_setg_file_open(), which adds error reason to open failures:

(qemu) dump-guest-memory -p /sfmdkjf/foo
Could not open '/sfmdkjf/foo': No such file or directory
(qemu) 

Luiz Capitulino (9):
  error: add error_setg_file_open() helper
  rng-random: use error_setg_file_open()
  block: bdrv_reopen_prepare(): use error_setg_file_open()
  block: mirror_complete(): use error_setg_file_open()
  blockdev: use error_setg_file_open()
  cpus: use error_setg_file_open()
  dump: qmp_dump_guest_memory(): use error_setg_file_open()
  savevm: qmp_xen_save_devices_state(): use error_setg_file_open()
  qerror: drop QERR_OPEN_FILE_FAILED macro
