[PATCH v2] usb: host: xhci-plat: keep runtime active when remove host

by Li Jun

While remove host(e.g. for USB role switch from host to device), if runtime pm is enabled by user, below oops are occurs at dwc3 and cdns3 platform. Keep the xhci-plat device being active during remove host fixes them. oops1: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000240 Mem abort info: ESR = 0x96000004

[PATCH stable-5.4.y] net: dsa: Do not make user port errors fatal

by Florian Fainelli

commit 86f8b1c01a0a537a73d2996615133be63cdf75db upstream Prior to 1d27732f411d ("net: dsa: setup and teardown ports"), we would not treat failures to set-up an user port as fatal, but after this commit we would, which is a regression for some systems where interfaces may be declared in the Device Tree, but the underlying hardware may not be present (pluggable daughter cards for instance).

[PATCH 1/1] usb: host: xhci-plat: keep runtime active when remove host

by Peter Chen

From: Li Jun <jun.li(a)nxp.com> While remove host(e.g. for USB role switch from host to device), if runtime pm is enabled by user, below oops are occurs at dwc3 and cdns3 platform.

[patch 2/7] epoll: call final ep_events_available() check under the lock

by Andrew Morton

From: Roman Penyaev <rpenyaev(a)suse.de> Subject: epoll: call final ep_events_available() check under the lock There is a possible race when ep_scan_ready_list() leaves ->rdllist and ->obflist empty for a short period of time although some events are pending. It is quite likely that ep_events_available() observes empty lists and goes to sleep. Since 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll") we are conservative in wakeups (there is only one place for wakeup and this is ep_poll_callback()), thus ep_events_available() must always observe correct state of two lists. The easiest and correct way is to do the final check under the lock. This does not impact the performance, since lock is taken anyway for adding a wait entry to the wait queue. The discussion of the problem can be found here: https://lore.kernel.org/linux-fsdevel/a2f22c3c-c25a-4bda-8339-a7bdaf17849e@… In this patch barrierless __set_current_state() is used. This is safe since waitqueue_active() is called under the same lock on wakeup side. Short-circuit for fatal signals (i.e. fatal_signal_pending() check) is moved to the line just before actual events harvesting routine. This is fully compliant to what is said in the comment of the patch where the actual fatal_signal_pending() check was added: c257a340ede0 ("fs, epoll: short circuit fetching events if thread has been killed").

[patch 1/7] mm, memcg: fix inconsistent oom event behavior

by Andrew Morton

From: Yafang Shao <laoar.shao(a)gmail.com> Subject: mm, memcg: fix inconsistent oom event behavior A recent commit 9852ae3fe529 ("mm, memcg: consider subtrees in memory.events") changes the behavior of memcg events, which will consider subtrees in memory.events. But oom_kill event is a special one as it is used in both cgroup1 and cgroup2. In cgroup1, it is displayed in memory.oom_control. The file memory.oom_control is in both root memcg and non root memcg, that is different with memory.event as it only in non-root memcg. That commit is okay for cgroup2, but it is not okay for cgroup1 as it will cause inconsistent behavior between root memcg and non-root memcg. Here's an example on why this behavior is inconsistent in cgroup1. root memcg / memcg foo / memcg bar Suppose there's an oom_kill in memcg bar, then the oon_kill will be root memcg : memory.oom_control(oom_kill) 0 / memcg foo : memory.oom_control(oom_kill) 1 / memcg bar : memory.oom_control(oom_kill) 1 For the non-root memcg, its memory.oom_control(oom_kill) includes its descendants' oom_kill, but for root memcg, it doesn't include its descendants' oom_kill. That means, memory.oom_control(oom_kill) has different meanings in different memcgs. That is inconsistent. Then the user has to know whether the memcg is root or not. If we can't fully support it in cgroup1, for example by adding memory.events.local into cgroup1 as well, then let's don't touch its original behavior.
