Self-NACK on this one. This results in a ton of warnings:
include/linux/fs.h:727: warning: ???__section__??? attribute does not apply to types In file included from include/linux/debugfs.h:18, from kernel/trace/trace_probe.h:28, from kernel/trace/trace_kprobe.c:23: include/linux/fs.h:727: warning: ???__section__??? attribute does not apply to types
And that leaves me with the task of figuring out if/why this actually helps.
