Kent, thx for handling this so quickly. If you want to do me a favor, please in the future include a "Link:" or "Closes:" tag with a URL to the report in cases like this, as explained in the docs (it's important for regression tracking, but also for future code archeologists); checkpatch should have pointed this out for this patch.
Anyway, no big deal here, let me tell regzbot directly about the fix:
#regzbot fix: bcachefs: Fix build errors with gcc 10
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
