do_hbm_test.sh:
The comment incorrectly used "upcomming" instead of "upcoming".

hbm.c
The comment incorrectly used "Managment" instead of "Management".
The comment incorrectly used "Currrently" instead of "Currently".

tcp_cong_kern.c
The comment incorrectly used "deteremined" instead of "determined".

tracex1.bpf.c
The comment incorrectly used "loobpack" instead of "loopback".

mtty.c
The comment incorrectly used "atleast" instead of "at least".
