[ Upstream commit 14bb1e8c8d4ad5d9d2febb7d19c70a3cf536e1e5 ]

Recently, I frequently hit the following test failure:

[root@arch-fb-vm1 bpf]# ./test_progs -n 33/1 test_lookup_update:PASS:skel_open 0 nsec [...] test_lookup_update:PASS:sync_rcu 0 nsec test_lookup_update:FAIL:map1_leak inner_map1 leaked! #33/1 btf_map_in_map/lookup_update:FAIL #33 btf_map_in_map:FAIL

In the test, after map is closed and then after two rcu grace periods, it is assumed that map_id is not available to user space.

But the above assumption cannot be guaranteed. After zero or one or two rcu grace periods in different siturations, the actual freeing-map-work is put into a workqueue. Later on, when the work is dequeued, the map will be actually freed. See bpf_map_put() in kernel/bpf/syscall.c.

By using workqueue, there is no ganrantee that map will be actually freed after a couple of rcu grace periods. This patch removed such map leak detection and then the test can pass consistently.

Using a struct_group seems to reliably avoid the warning and not make the code much uglier. The combined memset() should even save a couple of cpu cycles.

trace_drop_common() is called with preemption disabled, and it acquires a spin_lock. This is problematic for RT kernels because spin_locks are sleeping locks in this configuration, which causes the following splat:

trace_drop_common() also disables interrupts, but this is a minor issue because we could easily replace it with a local_lock.

Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic context.

This device sometimes doesn't send touch release signals when moving from >=4 fingers to <4 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.

MT_QUIRK_FORCE_MULTI_INPUT is not necessary for this device, but does no harm.

Duplicate of commit 0db117359e47 ("HID: add quirk for 03f0:464a HP Elite Presenter Mouse"), but in a slightly better way.

This time we actually change the application collection, making clearer for userspace what the second mouse is.

Note that having both hid-quirks fix and this HID-BPF fix is not a problem at all.
