Jann Horn a2ac97c78b getcwd.3: Note behavior for unreachable current working directory 
For the code that does this, see fs/dcache.c, search for
"prepend_unreachable".

Test case to demonstrate:

$ cat getcwd.c

int main(void) {
  unshare(CLONE_NEWUSER | CLONE_NEWNS);
  chdir("/usr");
  chroot("bin");

  printf("current directory: \"%s\"\n", get_current_dir_name());

  char *real = realpath(".", NULL);
  printf("realpath of .: \"%s\"\n", real ? real : "{none}");
  real = realpath("../home/jann/.ssh", NULL);
  printf("realpath of path: \"%s\"\n", real ? real : "{none}");

  return 0;
}
$ cat getcwd_test.c

int main(void) {
  unshare(CLONE_NEWUSER | CLONE_NEWNS);
  chdir("/usr");
  chroot("bin");
  printf("current directory: \"%s\"\n", get_current_dir_name());
  return 0;
}
$ gcc -o getcwd_test getcwd_test.c -Wall
$ ./getcwd_test
current directory: "(unreachable)/usr"

realpath.3 doesn't currently seem to handle this
case in a sane way, so I'm not going to document
its behavior yet. I'll report that as a bug instead.

David Rientjes 31ddc55d25 madvise.2: Specify MADV_REMOVE returns EINVAL for hugetlbfs 
madvise(2) actually returns with error EINVAL for MADV_REMOVE
when used for hugetlb VMAs, not EOPNOTSUPP, and this has been
the case since MADV_REMOVE was introduced in commit f6b3ec238d12
("madvise(MADV_REMOVE): remove pages from tmpfs shm backing
store").

Specify the exact behavior.
