由 Naoya Horiguchi 提交于
When a memory error happens on an in-use page or (free and in-use) hugepage, the victim page is isolated with its refcount set to one. When you try to unpoison it later, unpoison_memory() calls put_page() for it twice in order to bring the page back to free page pool (buddy or free hugepage list). However, if another memory error occurs on the page which we are unpoisoning, memory_failure() returns without releasing the refcount which was incremented in the same call at first, which results in memory leak and unconsistent num_poisoned_pages statistics. This patch fixes it.

Commit 284f39af ("mm: memcg: push !mm handling out to page cache charge function") explicitly checks for page cache charges without any mm context (from kernel thread context[1]). This seemed to be the only possible case where memory could be charged without mm context so commit 03583f1a ("memcg: remove unnecessary !mm check from try_get_mem_cgroup_from_mm()") removed the mm check from get_mem_cgroup_from_mm().

In some testing I ran today (some fio jobs that spread over two nodes), we end up spending 40% of the time in filemap_check_errors(). That smells fishy. Looking further, this is basically what happens: blkdev_aio_read() generic_file_aio_read() filemap_write_and_wait_range() if (!mapping->nr_pages) filemap_check_errors() and filemap_check_errors() always attempts two test_and_clear_bit() on the mapping flags, thus dirtying it for every single invocation. The patch below tests each of these bits before clearing them, avoiding this issue. In my test case (4-socket box), performance went from 1.7M IOPS to 4.0M IOPS.

ALB learning packets are currentlyalways sent using the slave mac address for all vlans configured on top of bond. This is not always correct, as vlans may change their mac address. This patch introduced a concept of strict matching where the source of learning packets can either strictly match the address passed in, or it can determine a more correct address to use. There are 3 casese to consider: 1) Switchover. In this case, we have a new active slave and we need tell the switch about all addresses available on the slave. 2) Monitor. We'll periodically refresh learning info for all slaves. In this case, we refresh all addresses for current active, and just the slave address for other slaves. 3) Teaching of disabled adddress. This happens as part of the failover and in this case, we alwyas to use just the address provided.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc由 Linus Torvalds 提交于
Pull two powerpc fixes from Ben Herrenschmidt: "Here are a couple of fixes for 3.15. One from Anton fixes a nasty regression I introduced when trying to fix a loss of irq_work whose consequences is that we can completely lose timer interrupts on a CPU... not pretty. The other one is a change to our PCIe reset hook to use a firmware call instead of direct config space accesses to trigger a fundamental reset on the root port. This is necessary so that the FW gets a chance to disable the link down error monitoring, which would otherwise trip and cause subsequent fatal EEH error" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: irq work racing with timer interrupt can result in timer interrupt hang powerpc/powernv: Reset root port in firmware

This is a regression introduced by commit 33be6271 (net_sched: act: use standard struct list_head). It's not very easy to fix it as the code is a mess: if (old_r) memcpy(&cr, r, sizeof(cr)); else { memset(&cr, 0, sizeof(cr)); tcf_exts_init(&cr.exts, TCA_TCINDEX_ACT, TCA_TCINDEX_POLICE); } ... tcf_exts_change(tp, &cr.exts, &e); ... memcpy(r, &cr, sizeof(cr)); the above code should equal to: tcindex_filter_result_init(&cr); if (old_r) cr.res = r->res; ... if (old_r) tcf_exts_change(tp, &r->exts, &e); else tcf_exts_change(tp, &cr.exts, &e); ... r->res = cr.res; after this change, since there is no need to copy struct tcf_exts. And it also fixes other places zero'ing struct's contains struct tcf_exts.

Pull xfs fixes from Dave Chinner: "Code inspection of the XFS error number sign translations found a bunch of issues, including returning incorrectly signed errors for some data integrity operations. These leak to userspace and result in applications not getting the errors correctly reported. Hence they need fixing sooner rather than later. A couple of the bugs are in data integrity operations, a couple more are in the new COLLAPSE_RANGE code. One of these came in through a recent ext4 merge and so I had to update the base tree to 3.15-rc5 before fixing the issues" * tag 'xfs-for-linus-3.15-rc6' of git://oss.sgi.com/xfs/xfs: xfs: list_lru_init returns a negative error xfs: negate xfs_icsb_init_counters error value xfs: negate mount workqueue init error value xfs: fix wrong err sign on xfs_set_acl() xfs: fix wrong errno from xfs_initxattrs xfs: correct error sign on COLLAPSE_RANGE errors xfs: xfs_commit_metadata returns wrong errno xfs: fix incorrect error sign in xfs_file_aio_read xfs: xfs_dir_fsync() returns positive errno
