PageError really only has meaning within a particular subsystem. Nothing looks at this bit in the core kernel code, and ceph itself doesn't care about it. Don't bother setting the PageError bit on error. Signed-off-by:

Currently it calls pagevec_lookup_range_nr_tag(), but that may be inefficient, as we might end up having to search several times as we get down to looking for fewer pages to fill the array. Thus spake Willy: "I think ceph is misusing pagevec_lookup_range_nr_tag(). Let's suppose you get a range which is AAAAbbbbAAAAbbbbAAAAbbbbbbbb(...)bbbbAAAA and you try to fetch max_pages=13. First loop will get AAAAbbbbAAAAb and have 8 locked_pages. The next call will get bbbAA and now locked_pages=10. Next call gets AAb ... and now you're iterating your way through all the 'b' one page at a time until you find that first A." 'A' here refers to pages that are eligible for writeback and 'b' represents ones that aren't (for whatever reason). Not capping the number of return pages may mean that we sometimes find more pages than are needed, but the extra references will just get put at the end. Ceph is also the only caller of pagevec_lookup_range_nr_tag(), so this change should allow us to eliminate that call as well. That will be done in a follow-on patch. Reported-by:

In client for each inode, it may have many opened files and may have been pinned in more than one MDS servers. And some inodes are idle, which have no any opened files. This patch will show these metrics in the debugfs, likes: item total ----------------------------------------- opened files / total inodes 14 / 5 pinned i_caps / total inodes 7 / 5 opened inodes / total inodes 3 / 5 Will send these metrics to ceph, which will be used by the `fs top`, later.

This special casing was added in 7ce469a5 (ceph: fix splice read for no Fc capability case). The confirm callback for ITER_PIPE expects that the page is Uptodate and returns an error otherwise. A simpler workaround is just to use the Uptodate bit, which has no meaning for anonymous pages. Rip out the special casing for ITER_PIPE and just SetPageUptodate before we copy to the iter.

Yan, Zheng authored
Since nautilus, MDS tracks dirfrags whose child inodes have caps in open file table. When MDS recovers, it prefetches all of these dirfrags. This avoids using backtrace to load inodes. But dirfrags prefetch may load lots of useless inodes into cache, and make MDS run out of memory. Recent MDS adds an option that disables dirfrags prefetch. When dirfrags prefetch is disabled. Recovering MDS only prefetches corresponding dir inodes. Including inodes' parent/d_name in cap reconnect message can help MDS to load inodes into its cache. Signed-off-by:

When memory is hotplug added or removed the min_free_kbytes should be recalculated based on what is expected by khugepaged. Currently after hotplug, min_free_kbytes will be set to a lower default and higher default set when THP enabled is lost. This change restores min_free_kbytes as expected for THP consumers.

There have been elusive reports of filemap_fault() hitting its VM_BUG_ON_PAGE(page_to_pgoff(page) != offset, page) on kernels built with CONFIG_READ_ONLY_THP_FOR_FS=y. Suren has hit it on a kernel with CONFIG_READ_ONLY_THP_FOR_FS=y and CONFIG_NUMA is not set: and he has analyzed it down to how khugepaged without NUMA reuses the same huge page after collapse_file() failed (whereas NUMA targets its allocation to the respective node each time). And most of us were usually testing with CONFIG_NUMA=y kernels. collapse_file(old start) new_page = khugepaged_alloc_page(hpage) __SetPageLocked(new_page) new_page->index = start // hpage->index=old offset new_page->mapping = mapping xas_store(&xas, new_page) filemap_fault page = find_get_page(mapping, offset) // if offset falls inside hpage then // compound_head(page) == hpage lock_page_maybe_drop_mmap() __lock_page(page) // collapse fails xas_store(&xas, old page) new_page->mapping = NULL unlock_page(new_page) collapse_file(new start) new_page = khugepaged_alloc_page(hpage) __SetPageLocked(new_page) new_page->index = start // hpage->index=new offset new_page->mapping = mapping // mapping becomes valid again // since compound_head(page) == hpage // page_to_pgoff(page) got changed VM_BUG_ON_PAGE(page_to_pgoff(page) != offset) An initial patch replaced __SetPageLocked() by lock_page(), which did fix the race which Suren illustrates above. But testing showed that it's not good enough: if the racing task's __lock_page() gets delayed long after its find_get_page(), then it may follow collapse_file(new start)'s successful final unlock_page(), and crash on the same VM_BUG_ON_PAGE. It could be fixed by relaxing filemap_fault()'s VM_BUG_ON_PAGE to a check and retry (as is done for mapping), with similar relaxations in find_lock_entry() and pagecache_get_page(): but it's not obvious what else might get caught out; and khugepaged non-NUMA appears to be unique in exposing a page to page cache, then revoking, without going through a full cycle of freeing before reuse. Instead, non-NUMA khugepaged_prealloc_page() release the old page if anyone else has a reference to it (1% of cases when I tested). Although never reported on huge tmpfs, I believe its find_lock_entry() has been at similar risk; but huge tmpfs does not rely on khugepaged for its normal working nearly so much as READ_ONLY_THP_FOR_FS does.
