Size of slab object already stored in cache->object_size. Note, that kmalloc() internally rounds up size of allocation, so object_size may be not equal to alloc_size, but, usually we don't need to know the exact size of allocated object. In case if we need that information, we still can figure it out from the report. The dump of shadow memory allows to identify the end of allocated memory, and thereby the exact allocation size.

Currently we call quarantine_reduce() for ___GFP_KSWAPD_RECLAIM (implied by __GFP_RECLAIM) allocation. So, basically we call it on almost every allocation. quarantine_reduce() sometimes is heavy operation, and calling it with disabled interrupts may trigger hard LOCKUP: NMI watchdog: Watchdog detected hard LOCKUP on cpu 2irq event stamp: 1411258 Call Trace: <NMI> dump_stack+0x68/0x96 watchdog_overflow_callback+0x15b/0x190 __perf_event_overflow+0x1b1/0x540 perf_event_overflow+0x14/0x20 intel_pmu_handle_irq+0x36a/0xad0 perf_event_nmi_handler+0x2c/0x50 nmi_handle+0x128/0x480 default_do_nmi+0xb2/0x210 do_nmi+0x1aa/0x220 end_repeat_nmi+0x1a/0x1e <<EOE>> __kernel_text_address+0x86/0xb0 print_context_stack+0x7b/0x100 dump_trace+0x12b/0x350 save_stack_trace+0x2b/0x50 set_track+0x83/0x140 free_debug_processing+0x1aa/0x420 __slab_free+0x1d6/0x2e0 ___cache_free+0xb6/0xd0 qlist_free_all+0x83/0x100 quarantine_reduce+0x177/0x1b0 kasan_kmalloc+0xf3/0x100 Reduce the quarantine_reduce iff direct reclaim is allowed.

We've had a report about soft lockups caused by lock bouncing in the soft reclaim path: BUG: soft lockup - CPU#0 stuck for 22s!

This is just pointless wasting of cycles and cache line bouncing during heavy parallel reclaim on large machines. The particular machine wasn't very healthy and most probably suffering from a memory leak which just caused the memory reclaim to trash heavily. But bouncing on the lock certainly didn't help... Fix this by optimistic lockless check and bail out early if the tree is empty. This is theoretically racy but that shouldn't matter all that much. First of all soft limit is a best effort feature and it is slowly getting deprecated and its usage should be really scarce. Bouncing on a lock without a good reason is surely much bigger problem, especially on large CPU machines.

Zhong Jiang has reported a BUG_ON from huge_pte_alloc hitting when he runs his database load with memory online and offline running in parallel. The reason is that huge_pmd_share might detect a shared pmd which is currently migrated and so it has migration pte which is !pte_huge. There doesn't seem to be any easy way to prevent from the race and in fact seeing the migration swap entry is not harmful. Both callers of huge_pte_alloc are prepared to handle them. copy_hugetlb_page_range will copy the swap entry and make it COW if needed. hugetlb_fault will back off and so the page fault is retries if the page is still under migration and waits for its completion in hugetlb_fault. That means that the BUG_ON is wrong and we should update it. Let's simply check that all present ptes are pte_huge instead.

In powerpc servers with large memory(32TB), we watched several soft lockups for hugepage under stress tests. The call traces are as follows: 1. get_page_from_freelist+0x2d8/0xd50 __alloc_pages_nodemask+0x180/0xc20 alloc_fresh_huge_page+0xb0/0x190 set_max_huge_pages+0x164/0x3b0 2. prep_new_huge_page+0x5c/0x100 alloc_fresh_huge_page+0xc8/0x190 set_max_huge_pages+0x164/0x3b0 This patch fixes such soft lockups. It is safe to call cond_resched() there because it is out of spin_lock/unlock section. Link: http://lkml.kernel.org/r/1469674442-14848-1-git-send-email-hejianet@gmail.comSigned-off-by:

Every swap-in anonymous page starts from inactive lru list's head. It should be activated unconditionally when VM decide to reclaim because page table entry for the page always usually has marked accessed bit. Thus, their window size for getting a new referece is 2 * NR_inactive + NR_active while others is NR_inactive + NR_active. It's not fair that it has more chance to be referenced compared to other newly allocated page which starts from active lru list's head. Johannes: : The page can still have a valid copy on the swap device, so prefering to : reclaim that page over a fresh one could make sense. But as you point : out, having it start inactive instead of active actually ends up giving it : *more* LRU time, and that seems to be without justification. Rik: : The reason newly read in swap cache pages start on the inactive list is : that we do some amount of read-around, and do not know which pages will : get used. : : However, immediately activating the ones that DO get used, like your patch : does, is the right thing to do.

According to Kirill Shutemov, the prefaulting code in do_fault_around() is supposed to take care of this, but missing error handling means that the allocation failure can go unnoticed. We don't need to return VM_FAULT_OOM (or any other error) here, since we can just let the normal fault path try again.

The testcase "mmaptruncate" in ocfs2 test suite always fails with ENOSPC error on small volume (say less than 10G). This testcase repeatedly performs "extend" and "truncate" on a file. Continuously, it truncates the file to 1/2 of the size, and then extends to 100% of the size. The main bitmap will quickly run out of space because the "truncate" code prevent truncate log from being flushed by ocfs2_schedule_truncate_log_flush(osb, 1), while truncate log may have cached lots of clusters. So retry to allocate after flushing truncate log when ENOSPC is returned. And we cannot reuse the deleted blocks before the transaction committed. Fortunately, we already have a function to do this - ocfs2_try_to_free_truncate_log(). Just need to remove the "static" modifier and put it into the right place. The "unlock"/"lock" code isn't elegant, but there seems to be no better option.

We encountered a bug from the customer, the user did a fsck.ocfs2 on the file system and exited unusually, the lockspace (with LVB size = 32) was left in the kernel space, next, the user mounted this file system, the kernel module did not create a new lockspace (LVB size = 64) via calling dlm_new_lockspace() function in mounting stage, just used the existing lockspace, created by the user space tool, this would lead the user was not able to mount this file system from the other nodes, with the error message like: dlm: 032F5......: config mismatch: 64,0 nodeid 177127961: 32,0 (mount.ocfs2,26981,46):ocfs2_dlm_init:2995 ERROR: status = -71 ocfs2_mount_volume:1881 ERROR: status = -71 ocfs2_fill_super:1236 ERROR: status = -71 The user found it very difficult to find the root cause, then, we brought out this patch to relieve such problem. First, we add one more flag in calling dlm_new_lockspace() function, to make sure the lockspace is created by kernel module itself, and this change will not affect the backward compatibility. Second, the obvious error message is reported in the kernel log, let the user be more easy to find the root cause. This patch will be used to insure the dlm lockspace is created by kernel module when mounting a ocfs2 file system. There are two ways to create a lockspace, from user space and kernel space, but the same name lockspaces probably have different lvblen lengths/flags. To avoid this mix using, we add one more flag DLM_LSFL_NEWEXCL, it will make sure the dlm lockspace is created by kernel module when mounting. Secondly, if a user space program (ocfs2-tools) is running on a file system, the user tries to mount this file system in the cluster, DLM module will return a -EEXIST or -EPROTO errno, we should give the user a obvious error message, then, the user can let that user space tool exit before mounting the file system again.

Pull btrfs updates from Chris Mason: "This pull is dedicated to Josef's enospc rework, which we've been testing for a few releases now. It fixes some early enospc problems and is dramatically faster. This also includes an updated fix for the delalloc accounting that happens after a fault in copy_from_user. My patch in v4.7 was almost but not quite enough" * 'for-linus-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: Btrfs: fix delalloc accounting after copy_from_user faults Btrfs: avoid deadlocks during reservations in btrfs_truncate_block Btrfs: use FLUSH_LIMIT for relocation in reserve_metadata_bytes Btrfs: fill relocation block rsv after allocation Btrfs: always use trans->block_rsv for orphans Btrfs: change how we calculate the global block rsv Btrfs: use root when checking need_async_flush Btrfs: don't bother kicking async if there's nothing to reclaim Btrfs: fix release reserved extents trace points Btrfs: add fsid to some tracepoints Btrfs: add tracepoints for flush events Btrfs: fix delalloc reservation amount tracepoint Btrfs: trace pinned extents Btrfs: introduce ticketed enospc infrastructure Btrfs: add tracepoint for adding block groups Btrfs: warn_on for unaccounted spaces Btrfs: change delayed reservation fallback behavior Btrfs: always reserve metadata for delalloc extents Btrfs: fix callers of btrfs_block_rsv_migrate Btrfs: add bytes_readonly to the spaceinfo at once
