You left some of the comparison warnings, can you please fix them?
move_pages_support.c: In function ‘alloc_pages_on_nodes’:
move_pages_support.c:70:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  for (i = 0; i < num; i++) {
                ^
move_pages_support.c:74:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  for (i = 0; i < num; i++) {
                ^
move_pages_support.c:91:8: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  if (i == num)
        ^~
symlink01.c: In function ‘get_tcs_info’:
symlink01.c:601:20: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  for (ctr = 0; ctr < (sizeof(all_tcses) / sizeof(struct tcses)); ctr++) {
                    ^

ebizzy.c: In function ‘thread_run’:
ebizzy.c:424:31: warning: unused parameter ‘arg’ [-Wunused-parameter]
 static void *thread_run(void *arg)
This one can be fixed with LTP_ATTRIBUTE_UNUSED
+#include "tst_common.h"
                               ^~~
-static void *thread_run(void *arg)
+static void *thread_run(void *arg LTP_ATTRIBUTE_UNUSED)


Kind regards,
Petr
