Subject: [PATCH] module loader should not complain about unknown symbol
Date: Mon, 12 Nov 2007 14:18:27 +0000 [thread overview]
Message-ID: <1194877107.5656.31.camel@localhost.localdomain> (raw)
If module A depends on module B and module B has not yet finished its
init() the module loader may print a warning about an unknown symbol.
This happens if module B is still in state MODULE_STATE_COMING,
as module A runs into resolve_symbol() for a symbol from module B.
resolve_symbol() return 0 in that case and causes the warning.
