Hi all, After merging the mmc tree, today's linux-next build (x86 allmodconfig) failed like this: /tmp/next/build/drivers/memstick/core/ms_block.c:158:6: error: implicit declaration of function 'bitmap_weight_eq'; did you mean 'bitmap_weight'? [-Werror=implicit-function-declaration] 158 | if (bitmap_weight_eq(msb->used_blocks_bitmap, msb->block_count, | ^~~~~~~~~~~~~~~~ | bitmap_weight Caused by commit 5f8d171cd8a93f ("memstick: replace bitmap_weight with bitmap_weight_eq where appropriate") I used the mmc tree from 20220217 instead.
