Hi all,
After merging the device-mapper tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
In file included from drivers/md/dm-dust.c:11:
drivers/md/dm-dust.c: In function 'dust_list_badblocks':
drivers/md/dm-dust.c:307:10: warning: zero-length gnu_printf format string [-Wformat-zero-length]
307 | DMEMIT("");
Mike and Bryan,
Should we just use "DMEMIT("\n")"? Maybe it's bad since this lead a
blank line...

include/linux/device-mapper.h:555:46: note: in definition of macro 'DMEMIT'
555 | 0 : scnprintf(result + sz, maxlen - sz, x))
