huge_count_read_write.c: In function 'write_read_with_huge_count':
huge_count_read_write.c:22:13: warning: variable 'ret' set but not used
[-Wunused-but-set-variable]
22 | int ret;
| ^~~
Remove unused 'ret' variable. The read() return value is not needed
here -- the test only checks that huge count reads/writes don't cause
kernel warnings.
