In this case it seems there is a function __get_fs_type earlier in the file
that gets matched instead:

  static struct file_system_type *__get_fs_type(const char *name, int len)
  {
  ...
  }

  struct file_system_type *get_fs_type(const char *name)
  {
  ...
  }

You can try for example:

$ git log -L ':[*]get_fs_type:fs/filesystems.c'  fs/filesystems.c | grep ^commit
$ git log -L ':[^_]get_fs_type:fs/filesystems.c' fs/filesystems.c | grep ^commit
$ git log -L ':\bget_fs_type:fs/filesystems.c'   fs/filesystems.c | grep ^commit
