* Fix a multipath device failure that reads "blk_cloned_rq_check_limits: over max size limit" which can occur when kernel function bio_get_nr_vecs() returns a value which is larger than the value of max sectors of the block device.<br>

I ran into this issue the other day even with the echo "4096" ><br>
/sys/block/$ii/queue/max_<wbr>sectors_kb; in place. I have always made that<br>
larger to get to the 2M IO size. So I never really seen this issue<br>
until the other day. I may have triggered it myself because I was<br>
adding new storage.<br>
<br>
Was wondering what version of GPFS fixes this. I really do not want to<br>
step back to and older kernel version.<br>
<br>
Thanks<br>
Matt<br>
