These patches came up because I was looking for the location of the declaration of the buffer used in kernel/params.c struct kernel_param_ops .get functions. I didn't find it. I want to see if it's appropriate to convert the sprintf family of functions used in these .get functions to sysfs_emit. Patches submitted here: https://lore.kernel.org/lkml/5d606519698ce4c8f1203a2b35797d8254c6050a.1600285923.git.joe@xxxxxxxxxxx/T/ Anyone know if it's appropriate to change the sprintf-like uses in these functions to sysfs_emit and/or sysfs_emit_at?
