• Status: CONFIRMED

[Description Agostino Sarubbo 2020-04-04 13:33:01 UTC]

This is an auto-filled bug because dev-lang/python fails to compile on s390. Feel free to adjust the summary to clarify the exact issue. Attached build log and emerge --info

Given the exotic arch, my first guess would be a kernel bug.

I am unblocking the stable request because this is almost certainly arch-specific.

Please compile/run the attached program to test fcntl(fd, F_NOTIFY, DN_MULTISHOT).

If this fails, this is definitely a kernel problem.

It fails with:

fcntl: Invalid argument

We really need to upgrade to a newer version of 5.4.x on our machines first.
