2021-02-24mm/slub: disable user tracing for kmemleak caches by defaultJohannes Berg
If kmemleak is enabled, it uses a kmem cache for its own objects. These objects are used to hold information kmemleak uses, including a stack trace. If slub_debug is also turned on, each of them has *another* stack trace, so the overhead adds up, and on my tests (on ARCH=um, admittedly) 2/3rds of the allocations end up being doing the stack tracing. Turn off SLAB_STORE_USER if SLAB_NOLEAKTRACE was given, to avoid storing the essentially same data twice.

2021-02-24mm, tracing: record slab name for kmem_cache_free()Jacob Wen
Currently, a trace record generated by the RCU core is as below. ... kmem_cache_free: call_site=rcu_core+0x1fd/0x610 ptr=00000000f3b49a66 It doesn't tell us what the RCU core has freed. This patch adds the slab name to trace_kmem_cache_free(). The new format is as follows. ... kmem_cache_free: call_site=rcu_core+0x1fd/0x610 ptr=0000000037f79c8d name=dentry ... kmem_cache_free: call_site=rcu_core+0x1fd/0x610 ptr=00000000f78cb7b5 name=sock_inode_cache ... kmem_cache_free: call_site=rcu_core+0x1fd/0x610 ptr=0000000018768985 name=pool_workqueue ... kmem_cache_free: call_site=rcu_core+0x1fd/0x610 ptr=000000006a6cb484 name=radix_tree_node We can use it to understand what the RCU core is going to free. For example, some users maybe interested in when the RCU core starts freeing reclaimable slabs like dentry to reduce memory pressure.

2021-02-24selftests/bpf: No need to drop the packet when there is no geneve optHangbin Liu
In bpf geneve tunnel test we set geneve option on tx side. On rx side we only call bpf_skb_get_tunnel_opt(). Since commit 9c2e14b48119 ("ip_tunnels: Set tunnel option flag when tunnel metadata is present") geneve_rx() will not add TUNNEL_GENEVE_OPT flag if there is no geneve option, which cause bpf_skb_get_tunnel_opt() return ENOENT and _geneve_get_tunnel() in test_tunnel_kern.c drop the packet. As it should be valid that bpf_skb_get_tunnel_opt() return error when there is not tunnel option, there is no need to drop the packet and break all geneve rx traffic. Just set opt_class to 0 in this test and keep returning TC_ACT_OK. Fixes: 933a741e3b82 ("selftests/bpf: bpf tunnel test.")

2021-02-24drm: Rename plane->state variables in atomic update and disableMaxime Ripard
Some drivers are storing the plane->state pointer in atomic_update and atomic_disable in a variable simply called state, while the state passed as an argument is called old_state. In order to ease subsequent reworks and to avoid confusing or inconsistent names, let's rename those variables to new_state. This was done using the following coccinelle script, plus some manual changes for mtk and tegra. @ plane_atomic_func @ identifier helpers; identifier func; @@ ( static const struct drm_plane_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; | static const struct drm_plane_helper_funcs helpers = { ..., .atomic_update = func, ..., }; ) @ moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_state = plane->state; ... } @ depends on moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + new_state ...> } @ moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; symbol oldstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *oldstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *newstate = plane->state; ... } @ depends on moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + newstate ...> } @ moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; symbol old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_pstate = plane->state; ... } @ depends on moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; identifier old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { <... - state + new_pstate ...> } Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210219120032.260676-8-maxime@cerno.tech

2021-02-24drm: Use state helper instead of plane state pointer in atomic_checkMaxime Ripard
Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_check hook, which would be the old plane state in the global atomic state since _swap_state hasn't happened when atomic_check is run. Use the drm_atomic_get_old_plane_state helper to get that state to make it more obvious.

The current atomic helpers have either their object state being passed as an argument or the full atomic state.
