Subject: [PATCH tip/core/rcu 0/6] kvfree_rcu() updates for v5.12-rc1
Date: Wed, 3 Mar 2021 16:10:44 -0800 [thread overview]
Message-ID: <20210304001044.GA22871@paulmck-ThinkPad-P72> (raw)
Hello!
This series contains kvfree_rcu() updates, most notably surrounding GPF
flags for memory allocation.
1. kvfree_rcu: Directly allocate page for single-argument case,
courtesy of "Uladzislau Rezki (Sony)".
2. kvfree_rcu: Use __GFP_NOMEMALLOC for single-argument kvfree_rcu().
3. kvfree_rcu: Make krc_this_cpu_unlock() use
raw_spin_unlock_irqrestore().
4. kvfree_rcu: Replace __GFP_RETRY_MAYFAIL by __GFP_NORETRY,
courtesy of "Uladzislau Rezki (Sony)".
5. kvfree_rcu: Use same set of GFP flags as does single-argument,
courtesy of "Uladzislau Rezki (Sony)".
6. Add kfree_rcu() single-argument scale test, courtesy of
"Uladzislau Rezki (Sony)".
Thanx, Paul
