[PATCH] detail in fs/block_dev.c

From: christophe barbe (christophe.barbe@inup.com)

in fs/block_dev.c block_read() function (in 2.2 and 2.4 series)

rblocks = blocks = (left + offset + blocksize - 1) >> blocksize_bits;
bhb = bhe = buflist;
if (filp->f_reada) {
        if (blocks < read_ahead[MAJOR(dev)] / (blocksize >> 9))
                blocks = read_ahead[MAJOR(dev)] / (blocksize >> 9);
        if (rblocks > blocks)
                blocks = rblocks;

The second test is false in all case and there's no concequences because the rblocks variable is never used.

So I've joined a patch (ok for 2.2.17 and 2.4.2) to remove rblocks.
