vmpressure is called synchronously from reclaim where the target_memcg is guaranteed to be alive but the eventfd is signaled from the work queue context. This means that memcg (along with vmpressure structure which is embedded into it) might go away while the work item is pending which would result in use-after-release bug. We have two possible ways how to fix this. Either vmpressure pins memcg before it schedules vmpr->work and unpin it in vmpressure_work_fn or explicitely flush the work item from the css_offline context (as suggested by Tejun). This patch implements the later one and it introduces vmpressure_cleanup which flushes the vmpressure work queue item item. It hooks into mem_cgroup_css_offline after the memcg itself is cleaned up.

zbud_alloc() incorrectly verifies the size of allocation limit. It should deny the allocation request greater than (PAGE_SIZE - ZHDR_SIZE_ALIGNED - CHUNK_SIZE), not (PAGE_SIZE - ZHDR_SIZE_ALIGNED) which has no remaining spaces for its buddy. There is no point in spending the entire zbud page storing only a single page, since we don't have any benefits. Signed-off-by:

active/inactive lru lists can contain unevicable pages (i.e. ramfs pages that have been placed on the LRU lists when first allocated), but these pages must not have PageUnevictable set - otherwise shrink_[in]active_list goes crazy: kernel BUG at /home/space/kas/git/public/linux-next/mm/vmscan.c:1122! 1090 static unsigned long isolate_lru_pages(unsigned long nr_to_scan, 1091 struct lruvec *lruvec, struct list_head *dst, 1092 unsigned long *nr_scanned, struct scan_control *sc, 1093 isolate_mode_t mode, enum lru_list lru) 1094 { ... 1108 switch (__isolate_lru_page(page, mode)) { 1109 case 0: ... 1116 case -EBUSY: ... 1121 default: 1122 BUG(); 1123 } 1124 } ... 1130 } __isolate_lru_page() returns EINVAL for PageUnevictable(page). For lru_add_page_tail(), it means we should not set PageUnevictable() for tail pages unless we're sure that it will go to LRU_UNEVICTABLE. Let's just copy PG_active and PG_unevictable from head page in __split_huge_page_refcount(), it will simplify lru_add_page_tail(). This will fix one more bug in lru_add_page_tail(): if page_evictable(page_tail) is false and PageLRU(page) is true, page_tail will go to the same lru as page, but nobody cares to sync page_tail active/inactive state with page. So we can end up with inactive page on active lru. The patch will fix it as well since we copy PG_active from head page. Signed-off-by:Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Acked-by:

As a result of commit 13f7f789 ("mm: pagevec: defer deciding which LRU to add a page to until pagevec drain time"), pages on unevictable lists can have both of PageActive and PageUnevictable set. This is not only confusing, but also corrupts page migration and shrink_[in]active_list. This patch fixes the problem by adding ClearPageActive before adding pages into unevictable list. It also cleans up VM_BUG_ONs. Signed-off-by:

Commit 3105b86a ("mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG") defined numabalancing_enabled to control the enabling and disabling of automatic NUMA balancing, but it is never used. I believe the intention was to use this in place of sched_feat_numa(NUMA). Currently, if SCHED_DEBUG is not defined, sched_feat_numa(NUMA) will never be changed from the initial "false".

vma_adjust() does vma_set_policy(vma, vma_policy(next)) and this is doubly wrong: 1. This leaks vma->vm_policy if it is not NULL and not equal to next->vm_policy. This can happen if vma_merge() expands "area", not prev (case 8). 2. This sets the wrong policy if vma_merge() joins prev and area, area is the vma the caller needs to update and it still has the old policy. Revert commit 1444f92c ("mm: merging memory blocks resets mempolicy") which introduced these problems. Change mbind_range() to recheck mpol_equal() after vma_merge() to fix the problem that commit tried to address. Signed-off-by:

Pablo Neira authored
Currently, it is not possible to use neither NLM_F_EXCL nor NLM_F_REPLACE from genetlink. This is due to this checking in genl_family_rcv_msg: if (nlh->nlmsg_flags & NLM_F_DUMP) NLM_F_DUMP is NLM_F_MATCH|NLM_F_ROOT. Thus, if NLM_F_EXCL or NLM_F_REPLACE flag is set, genetlink believes that you're requesting a dump and it calls the .dumpit callback. The solution that I propose is to refine this checking to make it stricter: if ((nlh->nlmsg_flags & NLM_F_DUMP) == NLM_F_DUMP) And given the combination NLM_F_REPLACE and NLM_F_EXCL does not make sense to me, it removes the ambiguity. There was a patch that tried to fix this some time ago (0ab03c2b netlink: test for all flags of the NLM_F_DUMP composite) but it tried to resolve this ambiguity in *all* existing netlink subsystems, not only genetlink. That patch was reverted since it broke iproute2, which is using NLM_F_ROOT to request the dump of the routing cache. Signed-off-by:

Don't test for having link and let hardware deal with this situation. Without this patch I see a machine running an -rt patched Linux being stuck in sch_direct_xmit when it looses link while there is still a packet to be sent. In this case the fec_enet_start_xmit routine returned NETDEV_TX_BUSY which makes the network stack reschedule the packet and so sch_direct_xmit calls fec_enet_start_xmit again. I failed to reproduce a complete hang without -rt, but I think the problem exists there, too. Signed-off-by:
