(Linux v2.6.20.6.)
The function md_autodetect_dev is defined in drivers/md/md.c. Its
declaration is on line 1443, outside of conditionals. However, both its
use on line 1455 and its definition on line 5600 are inside "#ifndef
MODULE" conditionals. So it seems obvious that the declaration should be
inside conditionals as well.
However, this function is separately declared and used in
fs/partitions/check.c but not inside the same conditional, which means if
md.c is compiled as a module, check.c will be referencing an undefined
symbol.
Should the conditionals around md_autodetect_dev be changed to make sure
CONFIG_BLK_DEV_MD=y, or does the function need to be extracted from md.c
so it can be used by check.c in any case?
