The patch titled
Subject: init: make unknown command line param message clearer
has been removed from the -mm tree. Its filename was
init-make-unknown-command-line-param-message-clearer.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andrew Halaney <ahalaney@xxxxxxxxxx>
Subject: init: make unknown command line param message clearer
The prior message is confusing users, which is the exact opposite of the
goal. If the message is being seen, one of the following situations is
happening:
1. the param is misspelled
2. the param is not valid due to the kernel configuration
3. the param is intended for init but isn't after the '--'
delineator on the command line
To make that more clear to the user, explicitly mention "kernel command
line" and also note that the params are still passed to user space to
avoid causing any alarm over params intended for init.
