The patch titled
Subject: taint: convert to indexed initialization
has been removed from the -mm tree. Its filename was
taint-convert-to-indexed-initialization.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: taint: convert to indexed initialization
This converts to using indexed initializers instead of comments, adds a
comment on why the taint flags can't be an enum, and make sure that no one
forgets to update the taint_flags when adding new bits.
