    xfs: fix xfs_debug warnings · 957935dc
    Christoph Hellwig 提交于
    For a CONFIG_XFS_DEBUG=n build gcc complains about statements with no
    effect in xfs_debug:
    
    fs/xfs/quota/xfs_qm_syscalls.c: In function 'xfs_qm_scall_trunc_qfiles':
    fs/xfs/quota/xfs_qm_syscalls.c:291:3: warning: statement with no effect
    
    The reason for that is that the various new xfs message functions have a
    return value which is never used, and in case of the non-debug build
    xfs_debug the macro evaluates to a plain 0 which produces the above
    warnings.  This can be fixed by turning xfs_debug into an inline function
    instead of a macro, but in addition to that I've also changed all the
    message helpers to return void as we never use their return values.
