Subject: [PATCH v5 0/2] Do not output logo on quiet boots
Date: Tue, 29 Jan 2019 13:43:48 +0000	[thread overview]
Message-ID: <20190129134350.24049-1-prarit@redhat.com> (raw)

On text-based systems the 'quiet' boot option will show printk levels
higher than CONSOLE_LOGLEVEL_QUIET.  The displaying of the Tux logo
during boot can cause some consoles to lose display data and as a result
confuse the end user.

Do not display the Tux logo on systems that are in 'quiet' boot.

v2: It helps to commit all my changes before sending them.  Remove extra
bracket.
v3: buildbot error fix: fbcon can be built as part of a module so export console_printk
v4: move console_printk change to separate patch, and drop logo cleanup
v5: Only set FBCON_LOGO_DONTSHOW for console loglevel
