The patch titled Subject: vm: adjust ifdef for TINY_RCU has been removed from the -mm tree. Its filename was vm-adjust-ifdef-for-tiny_rcu.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx> Subject: vm: adjust ifdef for TINY_RCU There is an ifdef in page_cache_get_speculative() that checks for !SMP and TREE_RCU, which has been an impossible combination since the advent of TINY_RCU. The ifdef enables a fastpath that is valid when preemption is disabled by rcu_read_lock() in UP systems, which is the case when TINY_RCU is enabled. This commit therefore adjusts the ifdef to generate the fastpath when TINY_RCU is enabled. Signed-off-by: Paul E.
