Subject: sparse errors in srcu.h
Date: Wed, 06 Dec 2006 10:50:14 +0100	[thread overview]
Message-ID: <45769256.1070400@ens-lyon.org> (raw)

Hi,

When running sparse checks on a file that ends up including srcu.h, we
get the following warnings:

    include/linux/srcu.h:52:44: error: undefined identifier 'sp'
    include/linux/srcu.h:52:44: error: bad constant expression
    include/linux/srcu.h:53:56: error: undefined identifier 'sp'
    include/linux/srcu.h:53:56: error: bad constant expression

It seems to be caused by the following lines:

    int srcu_read_lock(struct srcu_struct *sp) __acquires(sp);
    void srcu_read_unlock(struct srcu_struct *sp, int idx) __releases(sp);

which come from the following commit.

    commit 621934ee7ed5b073c7fd638b347e632c53572761

    [PATCH] srcu-3: RCU variant permitting read-side blocking


I was wondering if there is a way to fix those errors...

Thanks,
Brice
