    Subjectlinux-next: build warning after merge of the tip and rcu trees
    Hi all,

    After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
    produced this warning:

    kernel/debug/kdb/kdb_support.c: In function 'kdb_task_state_char':
    kernel/debug/kdb/kdb_support.c:639:2: warning: passing argument 1 of 'is_idle_task' discards 'const' qualifier from pointer target type [enabled by default]
    include/linux/sched.h:2097:20: note: expected 'struct task_struct *' but argument is of type 'const struct task_struct *'

    Introduced by commit 7fc20c5cbdd1 ("kdb: Make KDB use the new
    is_idle_task() API").

    This begs the question: Why does is_idle_task() not take a "const struct task_struct *"?
    --
    Cheers,
