MAINTAINERS: Update the MODULE SUPPORT section (2025-03-28 15:08:20 +0100)
----------------------------------------------------------------
Modules changes for 6.15-rc1
- Use RCU instead of RCU-sched
The mix of rcu_read_lock(), rcu_read_lock_sched() and preempt_disable()
in the module code and its users has been replaced with just
rcu_read_lock().
- The rest of changes are smaller fixes and updates.
The changes have been on linux-next for at least 2 weeks, with the RCU
cleanup present for 2 months. One performance problem was reported with the
RCU change when KASAN + lockdep were enabled, but it was effectively
addressed by the already merged ee57ab5a3212 ("locking/lockdep: Disable
KASAN instrumentation of lockdep.c").
