thanks for cleaning this up.
Oh, hm, I never saw the original email -- I'll check my Spam folder, it gets overly excited sometimes.
Just for completenes:
I have actually two patches submitted a while ago, but did not get any response so far, one that would make the test case work as it is:
[PATCH v10] exec: Fix dead-lock in de_thread with ptrace_attach https://lore.kernel.org/lkml/AM8PR10MB470801D01A0CF24BC32C25E7E40E9@AM8PR10M...
and my favorite one, that would fix the dead-lock altogether (and adjust the test case accordingly):
[PATCH v11] exec: Fix dead-lock in de_thread with ptrace_attach https://lore.kernel.org/lkml/AM8PR10MB470875B22B4C08BEAEC3F77FE4169@AM8PR10M...
This fell off my radar, but let's look at it again. Is this still an existing race after Eric's various refactorings? I assume so. Eric, can you looked at this case?
