[pve-devel] [PATCH common 1/2] REST environment: warn helpers: use warn instead of printing to stderr

[Fiona Ebner <f.ebner@proxmox.com>]

Like this, __WARN__ handlers will still be called. In particular,
daemons like pvestatd will set a __WARN__ handler and also log
warnings to syslog. The intention behind introducing log_warn() was to
make warnings more visible, not less, so fix the semantics to make
sure switching from warn to log_warn() does not have this unintended
side-effect.
