Subject: [PATCH tip/core/rcu 0/4] linked-list updates for 4.5
Date: Fri, 4 Dec 2015 16:15:05 -0800 [thread overview]
Message-ID: <20151205001505.GA26649@linux.vnet.ibm.com> (raw)
Hello!
This series contains a few linked-list updates:
1. Use WRITE_ONCE() when adding to lists and hlists (reported
by KTSAN).
2. Use READ_ONCE() when testing for empty lists (reported by
KTSAN).
3. Introduce generic list_splice_tail_init_rcu(), courtesy of
Petko Manolov.
4. Use WRITE_ONCE() when initializing list_head structures (reported
by KTSAN).
Thanx, Paul
