        aufs: plm mode, flags for si_read_lock()

        (This commit is just a part of "intorudce the pseudo-link maintenance
        mode" series)

        Handle the new flags AuLock_NOPLM/NOPLMW for most si_read_lock() call.
        New si_read_lock() waits the pseudo-link maintenance mode to exit, or
        return an error at once.

        Intorudce a new interface under procfs.
        Users have to update and install aufs2-util.git which handles the procfs
        entry.

        Now the pseudo-link feature totally depends upon CONFIG_PROC_FS.

        aufs: plm mode, remove plink ioctl, new au_plink_maint()

        (This commit is just a part of "intorudce the pseudo-link maintenance
        mode" series)

        Replace the current pseudo-link maintenance mode via ioctl by a new
        scheme using procfs interface. This patch doesn't contain the new
        interface. You will see it in later commits.

        Removing au_plink_ioctl(), AUFS_CTL_PLINK_MAINT and AUFS_CTL_PLINK_CLEAN
        means that users have to update and install aufs2-util.git too.

        - rewrite au_plink_maint_enter() and au_plink_maint_leave().
        - remove au_plink_maint_block().
        - remove au_plink_maint_leave() from aufs_release_dir().
        - extract a part of au_plink_ioctl() and create a new func
          au_plink_clean().

        aufs: bugfix, race around Magic SysRq, s_inodes and s_files

        Protect sb->s_inodes and ->s_files from aufs Magic SysRq handler.
        For allocating inodes, VFS calls s_op->alloc_inode() and then adds it to
        s_inodes. Also for destroying, VFS removes it from s_inodes first and
        then calls s_op->destory_inode().
        With this sequence, it is guranteed that the inode in s_inodes is always
        correct and we can refer struct au_iinfo.

        But for files, VFS adds the file object to s_files before calling
        f_op->open(), and calls ->release() before removing it from s_files.
        It means the file in s_files MAY be incorrect and we may not refer
        struct au_finfo.
        To support the file which is not initialized yet, aufs tests
        file->private_data. And to address the file which is released but still
        in s_files, aufs removes it from s_files first in file release operation.
