[pve-devel] [PATCH common] inotify: avoid cyclic use statement

[Fiona Ebner]

Commit e68ebda ("fix #545: interfaces: allow arbitrary bridge names in
network config") introduced a cyclic usage between
PVE::RESTEnvironment and PVE::INotify, making code like the following
fail:

> perl -e "use PVE::RESTEnvironment qw(log_warn);"

Note, including the PVE::INotify module first would still work, i.e.:

> perl -e "use PVE::INotify; use PVE::RESTEnvironment qw(log_warn);"

The rest of the PVE::INotify module alredy uses syslog(), which could
be used here as well to get rid of the cyclic usage. Wolfgang argued
that the whole point of commit e68ebda was to remove coupling between
the name and the type of the interface. If there still is some code
about a name starting with 'vmbr' being classified wrong, that should
rather be fixed. Because of the very commit, the frontend already
doesn't show e.g. a non-bridge with name 'vmbr7' in bridge selectors.

@Stefan: Do you have any good rationale to rather keep the check?
