Hi,
an answer from test mailing list.
>From kernel doc
" 1: 'G' if all modules loaded have a GPL or compatible license, 'P' if
any proprietary module has been loaded. Modules without a
MODULE_LICENSE or with a MODULE_LICENSE that is not recognised by
insmod as GPL compatible are assumed to be proprietary.
"
" 10: 'W' if a warning has previously been issued by the kernel.
(Though some warnings may set more specific taint flags.)
