Hi,
I have a (randconfig) build of 2.6.19-rc5-mm2 with:
CONFIG_DEBUG_READAHEAD=y
which selects DEBUG_FS, so DEBUG_FS=y, but DEBUG_FS depends on SYSFS, and SYSFS is not set in the randconfig.
This randconfig causes this build error:
fs/built-in.o: In function `debugfs_init': inode.c:(.init.text+0xdb2): undefined reference to `kernel_subsys'
so the question is: (How) can kconfig follow the dependency chain and either - prevent this odd config combination or - see that 'select DEBUG_FS' implies 'select SYSFS' and then enable SYSFS ?
I don't believe that the right answer is to add depends on SYSFS to DEBUG_READAHEAD.
.config is at http://oss.oracle.com/~rdunlap/configs/config-readahead-debugfs
