v1: https://lore.kernel.org/qemu-devel/20240325153313.526888-1-iii@linux.ibm.com/
v1 -> v2: Remove an unnecessary ifdef, add R-Bs (Richard).

Hi,

I noticed that while shmat() now works with /proc/self/maps,
shmat(NULL) got broken. This series fixes that along with two related
strace issues, and adds a test.

Best regards,
Ilya
