I noticed that the logic in the fadvise64_64 syscall is incorrect for partial pages. While first page of the region is correctly skipped if it is partial, the last page of the region is mistakenly discarded. This leads to problems for applications that read data in non-page-aligned chunks discarding already processed data between the reads. A somewhat misguided application that does something like write(XX bytes (non-page-alligned)); drop the data it just wrote; repeat gets a significant penalty in performance as a result.

This patch is based on https://patchwork.ozlabs.org/patch/574623/. Tejun submitted commit 23d11a58 ("workqueue: skip flush dependency checks for legacy workqueues") for the legacy create*_workqueue() interface. But some workq created by alloc_workqueue still reports warning on memory reclaim, e.g nvme_workq with flag WQ_MEM_RECLAIM set: workqueue: WQ_MEM_RECLAIM nvme:nvme_reset_work is flushing !WQ_MEM_RECLAIM events:lru_add_drain_per_cpu ------------[ cut here ]------------ WARNING: CPU: 0 PID: 6 at SoC/linux/kernel/workqueue.c:2448 check_flush_dependency+0xb4/0x10c ... check_flush_dependency+0xb4/0x10c flush_work+0x54/0x140 lru_add_drain_all+0x138/0x188 migrate_prep+0xc/0x18 alloc_contig_range+0xf4/0x350 cma_alloc+0xec/0x1e4 dma_alloc_from_contiguous+0x38/0x40 __dma_alloc+0x74/0x25c nvme_alloc_queue+0xcc/0x36c nvme_reset_work+0x5c4/0xda8 process_one_work+0x128/0x2ec worker_thread+0x58/0x434 kthread+0xd4/0xe8 ret_from_fork+0x10/0x50 That's because lru_add_drain_all() will schedule the drain work on system_wq, whose flag is set to 0, !WQ_MEM_RECLAIM.

Christian Borntraeger reported a kernel panic after corrupt page counts, and it turned out to be a regression introduced with commit aa88b68c ("thp: keep huge zero page pinned until tlb flush"), at least on s390. put_huge_zero_page() was moved over from zap_huge_pmd() to release_pages(), and it was replaced by tlb_remove_page(). However, release_pages() might not always be triggered by (the arch-specific) tlb_remove_page(). On s390 we call free_page_and_swap_cache() from tlb_remove_page(), and not tlb_flush_mmu() -> free_pages_and_swap_cache() like the generic version, because we don't use the MMU-gather logic. Although both functions have very similar names, they are doing very unsimilar things, in particular free_page_xxx is just doing a put_page(), while free_pages_xxx calls release_pages(). This of course results in very harmful put_page()s on the huge zero page, on architectures where tlb_remove_page() is implemented in this way. It seems to affect only s390 and sh, but sh doesn't have THP support, so the problem (currently) probably only exists on s390. The following quick hack fixed the issue: Link: http://lkml.kernel.org/r/20160602172141.75c006a9@thinkpad Signed-off-by:

When creating a private mapping of a hugetlbfs file, it is possible to unmap pages via ftruncate or fallocate hole punch. If subsequent faults repopulate these mappings, the reserve counts will go negative. This is because the code currently assumes all faults to private mappings will consume reserves. The problem can be recreated as follows: - mmap(MAP_PRIVATE) a file in hugetlbfs filesystem - write fault in pages in the mapping - fallocate(FALLOC_FL_PUNCH_HOLE) some pages in the mapping - write fault in pages in the hole This will result in negative huge page reserve counts and negative subpool usage counts for the hugetlbfs. Note that this can also be recreated with ftruncate, but fallocate is more straight forward. This patch modifies the routines vma_needs_reserves and vma_has_reserves to examine the reserve map associated with private mappings similar to that for shared mappings. However, the reserve map semantics for private and shared mappings are very different. This results in subtly different code that is explained in the comments.
