Robin Holt authored
On large memory machines it can take a few minutes to get through free_all_bootmem(). Currently, when free_all_bootmem() calls __free_pages_memory(), the number of contiguous pages that __free_pages_memory() passes to the buddy allocator is limited to BITS_PER_LONG. BITS_PER_LONG was originally chosen to keep things similar to mm/nobootmem.c. But it is more efficient to limit it to MAX_ORDER. base new change 8TB 202s 172s 30s 16TB 401s 351s 50s That is around 1%-3% improvement on total boot time. This patch was spun off from the boot time rfc Robin and I had been working on.

Since commit 13ece886 ("thp: transparent hugepage config choice"), transparent hugepage support is disabled by default, and TRANSPARENT_HUGEPAGE_ALWAYS is configured when TRANSPARENT_HUGEPAGE=y. And since commit d39d33c3 ("thp: enable direct defrag"), defrag is enable for all transparent hugepage page faults by default, not only in MADV_HUGEPAGE regions.

When ocfs2_write_cluster_by_desc() failed in ocfs2_write_begin_nolock() because of ENOSPC, it goes to out_quota, freeing data_ac(meta_ac). Then it calls ocfs2_try_to_free_truncate_log() to free space. If enough space freed, it will try to write again. Unfortunately, some error happenes before ocfs2_lock_allocators(), it goes to out and free data_ac(meta_ac) again.

We trigger a bug in __dlm_lockres_reserve_ast() when we parallel umount 4 nodes. The situation is as follows: 1) Node A migrate all lockres it owned(eg. lockres A) to other nodes say node B when it umounts. 2) Receiving MIG_LOCKRES message from A, Node B masters the lockres A with DLM_LOCK_RES_MIGRATING state set. 3) Then we umount ocfs2 on node B. It also should migrate lockres A to another node, say node C. But now, DLM_LOCK_RES_MIGRATING state of lockers A is not cleared. Node B triggered the BUG on lockres with state DLM_LOCK_RES_MIGRATING.

A parallel umount on 4 nodes triggered a bug in dlm_process_recovery_date(). Here's the situation: Receiving MIG_LOCKRES message, A node processes the locks in migratable lockres. It copys lvb from migratable lockres when processing the first valid lock. If there is a lock in the blocked list with the EX level, it triggers the BUG. Since valid lvbs are set when locks are granted with EX or PR levels, locks in the blocked list cannot have valid lvbs. Therefore I think we should skip the locks in the blocked list.

Any user process callers of wait_for_completion() except global init process might be chosen by the OOM killer while waiting for completion() call by some other process which does memory allocation. See CVE-2012-4398 "kernel: request_module() OOM local DoS" can happen. When such users are chosen by the OOM killer when they are waiting for completion() in TASK_UNINTERRUPTIBLE, the system will be kept stressed due to memory starvation because the OOM killer cannot kill such users. kthread_create() is one of such users and this patch fixes the problem for kthreadd by making kthread_create() killable - the same approach used for fixing CVE-2012-4398.
