[LTP] [PATCH] min_kver: Add kernel version requestions

[yangx.jy@fujitsu.com]

Hi Zhongyi,

Do you get any issue here?

It is unncessary to add version check because LTP has check the support 
of  preadv2/pwritev2:
1) Call preadv2/pwritev2 directly if glibc provides it.
2) Call syscall(__NR_preadv2/__NR_pwritev2) if glibc doesn't provides 
preadv2/pwritev.
3) Report TCONF if kernel doesn't support __NR_preadv2/__NR_pwritev2.

Please reference "include/lapi/preadv2.h"

Best Regards,
Xiao Yang
