[LTP] [PATCH] mmapstress01: Modify readbuf's type and define it to uchar_t

[Zeng Linggang <zenglg.jy@cn.fujitsu.com>]

readbuf is defined to char. That is different with the previous
defined. If readbuf's value is more than 127, that would be regarded
as negative number. And expbuf is uchar_t, the value is always
nonegative. That will make the test fail because the different data
type.
