Since commit d86d4aafd4fa22fa4cccb83253fb187b03f97f48, the pid
must be retrieved from current_thread.

The change has not been made in the function linux_read_offsets().

Hi Romain,
Thanks for updating the patch.

Before I push your commit in, a question to GDB maintainers, looks
Romain Naour doesn't have FSF copy right assignment, but this patch is
very simple, so IIUC, we can push it in without Romain's copy right
assignment record.

That's correct. You can push it using the "tiny patch" annotation
in the ChangeLog. See:
