We have no need to include <linux/debugfs.h> if the CONFIG_DEBUG_FS option is not set.

This patch breaks the build with debugfs enabled.

Hello Alex,
2015-07-14 11:11 GMT+06:00 Alex Deucher alexdeucher@gmail.com:
This patch breaks the build with debugfs enabled.
I've tried to built with CONFIG_DEBUG_FS={y/n} and it builds successfully. Did I miss something? Maybe I need to enable/disable anything else CONFIG_*?
Thank you.

Price question is why do you want to conditionally include this header in the first place?
If the kernel isn't build with CONFIG_DEBUG_FS we shouldn't use the defines, but otherwise they don't seem to hurt.

Thank you.
