Subject: [PATCH] merge_config.sh: Add option for allmodconfig
Date: Tue, 10 Dec 2019 20:09:14 +0800 [thread overview]
Message-ID: <1575979754-184896-1-git-send-email-john.garry@huawei.com> (raw)
Recently there has been some work in reporting and fixing bugs in booting
an allmodconfig kernel - here are a few examples:
https://lore.kernel.org/linux-edac/304df85b-8b56-b77e-1a11-aa23769f2e7c@huawei.com/T/#t
https://lore.kernel.org/linux-ide/bdf02e03-86a1-3d35-2908-28187f504495@huawei.com/T/#t
https://lore.kernel.org/netdev/CADYN=9LCPfbpwdTWKw03B22-y3Text=RWXW7XP7wJBHYsMOgrA@mail.gmail.com/
https://sourceforge.net/p/openipmi/mailman/message/36871567/
If we want to boot an allmodconfig kernel we may still want to force some
loadable modules built-in, like UART drivers. Or just still turn off some
configs.
So add an option to add add fragments to an allmodconfig kernel.
