One build issue comes up due to both mount.h included dev_in_maps.c
In file included from dev_in_maps.c:10:
/usr/include/sys/mount.h:35:3: error: expected identifier before numeric constant
35 | MS_RDONLY = 1, /* Mount read-only. */
| ^~~~~~~~~
In file included from dev_in_maps.c:13:
Remove one of them to solve conflict, another error comes up:
dev_in_maps.c:170:6: error: implicit declaration of function ‘mount’ [-Werror=implicit-function-declaration]
170 | if (mount(NULL, "/", NULL, MS_SLAVE | MS_REC, NULL) == -1) {
| ^~~~~
cc1: all warnings being treated as errors
and then , add sys_mount definition to solve it
After both above, dev_in_maps.c can be built correctly on my mache(gcc 10.2,glibc-2.32,kernel-5.10)
