Hi all, After merging the btrfs tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: ERROR: modpost: ".balance_dirty_pages_ratelimited_flags" [fs/btrfs/btrfs.ko] undefined! Caused by commit 145103680cd0 ("btrfs: make balance_dirty_pages nowait compatible") balance_dirty_pages_ratelimited_flags() is not currently exported to modules. I have used the btrfs tree from next-20220906 for today. -- Cheers, Stephen Rothwell
