  - memcg: bypass the reclaim and oom killer for dying tasks once oom_reaper is done At Meta, we are seeing
    instances where an OOM killed job is stuck in the exit path for several hours. In one particular case, the
    job was stuck for more than 8 hours and I had to manually remove the memory.max limits to allow the
    process to exit. The job was a single process job and had ~55 GiB memory.max and zswap enabled. It had
    almost 0 anon in memory and ~111 GiB in zswap compressed to ~51 GiB zswap pool (i.e. almost all of
    memory.current was zswap). Nothing was left on the LRUs to reclaim. On further inspection, I observed ~20k
    threads of that process stuck with the following stack: [<0>] mem_cgroup_out_of_memory+0x4e/0xa0 [<0>]
    charge_memcg+0x8bf/0x990 [<0>] mem_cgroup_swapin_charge_folio+0x4e/0x80 [<0>]

    [<0>] do_syscall_64+0x152/0x250 [<0>] entry_SYSCALL_64_after_hwframe+0x4b/0x53 In addition the dmesg was
    filled with Out of memory and no killable processes... messages. I have no idea why oom reaper was not
    able to reap/unmap the process. My guess is that since oom reaper tries to acquire mmap_lock in read mode
    limited number of times and then gives up, there might be a thread of that process which had mmap_lock in
    write mode at that time. My initial suspicion was the futex_cleanup and kernel page fault causing infinite
    fault and charge retries but that was put to rest in previous discussions happened on similar problem [1].
    My current theory is that it is just a simple slow serialization behind the oom_lock. Unlike page
    allocator, memcg charge code takes the oom_lock without the try. Though memcg oom code uses
    mutex_lock_killable(), note that in the call stack get_signal() consumes SIGKILL (or sigdelset(SIGKILL))
    before calling do_group_exit(). So this mutex_lock_killable() is just a mutex_lock() here. Therefore 10s
    of thousands of threads are waiting on oom_lock and one by one they get -EFAULT from get_user() in the
    futex cleanup code and bails out. Discussion from [1] led to commit a75ffa26122b (memcg, oom: do not
    bypass oom killer for dying tasks) which routes dying tasks into the OOM path precisely so the oom_reaper
    can reap their mm and free the memory asynchronously. But the reaper is best-effort and one-shot: if it
    cannot take mmap_lock for read (e.g. a sibling thread holds it for write) it sets MMF_OOM_SKIP and never
    retries, leaving only the glacial oom_lock-serialized synchronous drain. Once MMF_OOM_SKIP is set there is
    no more asynchronous reclaim coming for the mm, so a dying task charging against it has nothing left to
    wait for: it frees its memory only once it finishes exiting. Running reclaim and the (no-victim) OOM
    killer for it is then pointless, and doing it for 10s of thousands of exiting threads is what serializes
    them behind oom_lock. So before reclaim, if current is an OOM victim whose reaper is done, fail the
    charge. Reproduced with 20k threads, each parking a robust futex head on its own zswapped page, OOM-group-
    killed while a sibling holds mmap_lock for write so the reaper gives up and sets MMF_OOM_SKIP. Tested on
    next-20260728 and baseline show ~90 seconds exit time while with the patch the exit time reduced to ~3
    seconds. (CVE-2026-93241)
