Hi, Cyril
v3 -> v4: updated set_sys_tune() and get_sys_tune(), please comment.
There are several vm tunable files under /proc/sys/vm, I will compose
some cases for testing the basic functions of them. This patch is adding
the read/write/check functions to mem lib so that I can include them in
my testcases.
set_sys_tune(): set a long long integer value to a vm tunable file.
get_sys_tune(): get a long long integer value from a vm tunable file.
check_sys_tune(): check to confirm the value in tunable file meets our
expectation.
read_meminfo(): read the special value from /proc/meminfo.
Since most of the values in vm tunable files contain only single
integer, the functions I added only read/write long long values for now.
For those files not storing single interger (e.g. lowmem_reserve_ratio),
these functions will not be used in the case.
