Re: [PATCH] rcu: Replace rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)

Many of your patches, such as this one, all have the same exact
subject line.

This makes it impossible to scan the subject lines and have some
idea what area a commit makes changes.

I would really suggest that you use a subject prefix that references
the driver or subsystem, so for this one:

Subject: [PATCH N/M] infiniband: Use rcu_assign_pointer(x, NULL instead) of RCU_INIT_POINTER(x, NULL)

and likewise for all of your other patches.
