It's a 9p bug, sorry. tentative fix: https://lkml.kernel.org/r/[email protected] other thread with repro: https://lkml.kernel.org/r/CAHzjS_u_SYdt5=2gyo_dxzmkxzgmt-tfde_ueowg-hq5trc...@mail.gmail.com I'll send the fix to Linus once someone can confirm this works for this usecase as well (and try to improve our testing a bit... maybe just run the bpf test suite for starters) -- Dominique Martinet | Asmadeus
