Look at commit 3348e05a4f25489908d9f7ed4e80ac291ead18f4 almost 5 years
ago:
[PATCH] DEBUG_FS must depend on SYSFS
CONFIG_DEBUG_FS=y and CONFIG_SYSFS=n results in the following compile
error:
<-- snip -->
...
LD vmlinux
fs/built-in.o: In function `debugfs_init':
inode.c:(.init.text+0x31be): undefined reference to `kernel_subsys'
make: *** [vmlinux] Error 1
<-- snip -->
But, there is no "kernel_subsys" anymore, it is called kernel_kobj, and
is in kernel/ksysfs.c and always is built now, even if CONFIG_SYSFS is
disabled.
So it should be safe to remove that dependancy if you want to.
thanks,
