The patch titled
Subject: printk: mark printk_once test variable __read_mostly
has been removed from the -mm tree. Its filename was
printk-mark-printk_once-test-variable-__read_mostly.patch
This patch was dropped because it had testing failures
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: printk: mark printk_once test variable __read_mostly
It's only set once so mark it __read_mostly.
Neaten the alignment so it matches the rest of the pr_<level>_once
#defines too.
