perf/core: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
Author: Andreea-Cristina Bernat <bernat.ada@gmail.com> The use of “rcu_assign_pointer()” is NULLing out the pointer. According to RCU_INIT_POINTER()’s block comment: “1. This use of RCU_INIT_POINTER() is NULLing out the pointer” it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. The following Coccinelle semantic patch was used: @@ @@ – rcu_assign_pointer + …

af_decnet: Use time_after_eq
Author: Himangi Saraogi <himangi774@gmail.com> The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.
