Hi all, After merging the device-mapper tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/md/dm-vdo/io-factory.c: In function 'read_ahead': drivers/md/dm-vdo/io-factory.c:118:17: error: too few arguments to function 'dm_bufio_prefetch' 118 | dm_bufio_prefetch(reader->client, block_number, read_ahead); | ^~~~~~~~~~~~~~~~~ In file included from drivers/md/dm-vdo/io-factory.h:9, from drivers/md/dm-vdo/io-factory.c:6: include/linux/dm-bufio.h:86:6: note: declared here 86 | void dm_bufio_prefetch(struct dm_bufio_client *c, | ^~~~~~~~~~~~~~~~~ drivers/md/dm-vdo/io-factory.c: In function 'position_reader': drivers/md/dm-vdo/io-factory.c:182:24: error: too few arguments to function 'dm_bufio_read' 182 | data = dm_bufio_read(reader->client, block_number, &buffer); | ^~~~~~~~~~~~~ include/linux/dm-bufio.h:64:7: note: declared here 64 | void *dm_bufio_read(struct dm_bufio_client *c, sector_t block, | ^~~~~~~~~~~~~ Caused by commit 82da73bac1ee ("dm vdo: add deduplication index storage interface") interacting with commit 3be93545346e ("dm bufio: Support IO priority") I have used the device-mapper tree from next-20240206 for today. -- Cheers, Stephen Rothwell
