Running "make kselftest" results in several errors like these:
pidfd_fdinfo_test.c:231:36: error: ‘MS_REC’ undeclared (first use in this function) 231 | r = mount(NULL, "/", NULL, MS_REC | MS_PRIVATE, 0);
pidfd_fdinfo_test.c:231:45: error: ‘MS_PRIVATE’ undeclared (first use in this function); did you mean ‘MAP_PRIVATE’? 231 | r = mount(NULL, "/", NULL, MS_REC | MS_PRIVATE, 0);
pid_max.c:48:9: warning: implicit declaration of function ‘umount2’; did you mean ‘SYS_umount2’? [-Wimplicit-function-declaration] 48 | umount2("/proc", MNT_DETACH);
This patch adds the <sys/mount.h> include in pidfd_fdinfo_test.c and pid_max.c files to find the variables MS_REC, MS_PRIVATE, MNT_DETACH.
