- Invoke MOD_QUIESCE on all modules in a linker file (kld) before
unloading any modules. As a result, if any module veto's an unload request via MOD_QUIESCE, the entire set of modules for that linker file will remain loaded and active now rather than leaving the kld in a weird state where some modules are loaded and some are unloaded. - This also moves the logic for handling the "forced" unload flag out of kern_module.c and into kern_linker.c which is a bit cleaner. - Add a module_name() routine that returns the name of a module and use that instead of printing pointer values in debug messages when a module fails MOD_QUIESCE or MOD_UNLOAD. MFC after: 1 month
