Hi all,
As I proposed:
http://marc.info/?l=linux-arm-kernel&m=144944469805753
, we can define a __private modifier for sparse to detect misuses of private members of structs. This could make maintenace a little easier and prevent some potential bugs.
This patchset serves as a POC and consists of three patches:
1. Introduce __private and related macro, also improve compiler.h a litte bit
2. Privatize rcu_node::lock
3. Privatize irq_common_data::state_use_accessors
This patchset is against
-rcu/rcu/next 5f343fc7f0ce7edfe344e7cc5afdfe145a18f802
because this depends on commits:
"rcu: Create transitive rnp->lock acquisition functions"
and
"rcu: Add transitivity to remaining rcu_node ->lock acquisitions
I tried to use 0day to test this, but seems the email transfer from 0day to my mail box is very slow recently, so I haven't received a recent result yet. But as one can see, this patchset doesn't have any functional modification, the 0day may not find anything interesting ;-)
Looking forward to any suggestion, question and comment ;-)
Regards, Boqun
