      mm/rmap: try_to_migrate() skip zone_device !device_private · 6c855fce
      Hugh Dickins authored
      
      
      I know nothing about zone_device pages and !device_private pages; but if
      try_to_migrate_one() will do nothing for them, then it's better that
      try_to_migrate() filter them first, than trawl through all their vmas.

      mm/rmap: fix new bug: premature return from page_mlock_one() · 023e1a8d
      Hugh Dickins authored
      In the unlikely race case that page_mlock_one() finds VM_LOCKED has been
      cleared by the time it got page table lock, page_vma_mapped_walk_done()
      must be called before returning, either explicitly, or by a final call
      to page_vma_mapped_walk() - otherwise the page table remains locked.

      mm/rmap: fix old bug: munlocking THP missed other mlocks · d9770fcc
      Hugh Dickins authored
      The kernel recovers in due course from missing Mlocked pages: but there
      was no point in calling page_mlock() (formerly known as
      try_to_munlock()) on a THP, because nothing got done even when it was
      found to be mapped in another VM_LOCKED vma.
      
      It's true that we need to be careful: Mlocked accounting of pte-mapped
      THPs is too difficult (so consistently avoided); but Mlocked accounting
      of only-pmd-mapped THPs is supposed to work, even when multiple mappings
      are mlocked and munlocked or munmapped.  Refine the tests.
      
      There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
      page_mlock_one() does not even have to worry about that complication.
      
      (I said the kernel recovers: but would page reclaim be likely to split
      THP before rediscovering that it's VM_LOCKED? I've not followed that up)
      
      Fixes: 9a73f61b

      mm/rmap: fix comments left over from recent changes · 64b586d1
      Hugh Dickins authored
      
      
      Parallel developments in mm/rmap.c have left behind some out-of-date
      comments: try_to_migrate_one() also accepts TTU_SYNC (already commented
      in try_to_migrate() itself), and try_to_migrate() returns nothing at
      all.
      
      TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it
      in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so
      delete the "recently referenced" comment from try_to_unmap_one() (once
      upon a time the comment was near the removed codeblock, but they drifted
      apart).

      Pull more perf tool updates from Arnaldo Carvalho de Melo:
       "New features:
      
         - Enable use of BPF counters with 'perf stat --for-each-cgroup',
           using per-CPU 'cgroup-switch' events with an attached BPF program
           that does aggregation per-cgroup in the kernel instead of using
           per-cgroup perf events.
      
         - Add Topdown metrics L2 events as default events in 'perf stat' for
           systems having those events.
      
        Hardware tracing:
      
         - Add a config for max loops without consuming a packet in the Intel
           PT packet decoder, set via 'perf config intel-pt.max-loops=N'
      
        Hardware enablement:
      
         - Disable misleading NMI watchdog message in 'perf stat' on hybrid
           systems such as Intel Alder Lake.
      
         - Add a dummy event on hybrid systems to collect metadata records.
      
         - Add 24x7 nest metric events for the Power10 platform.
      
        Fixes:
      
         - Fix event parsing for PMUs starting with the same prefix.
      
         - Fix the 'perf trace' 'trace' alias installation dir.
      
         - Fix buffer size to report iregs in perf script python scripts,
           supporting the extended registers in PowerPC.
      
         - Fix overflow in elf_sec__is_text().
      
         - Fix 's' on source line when disasm is empty in the annotation TUI,
           accessible via 'perf annotate', 'perf report' and 'perf top'.
      
         - Plug leaks in scandir() returned dirent entries in 'perf test' when
           sorting the shell tests.
      
         - Fix --task and --stat with pipe input in 'perf report'.
      
         - Fix 'perf probe' use of debuginfo files by build id.
      
         - If a DSO has both dynsym and symtab ELF sections, read from both
           when loading the symbol table, fixing a problem processing Fedora
           32 glibc DSOs.
      
        Libraries:
      
         - Add grouping of events to libperf, from code in tools/perf,
           allowing libperf users to use that mode.
      
        Misc:
      
         - Filter plt stubs from the 'perf probe --functions' output.
      
         - Update UAPI header copies for asound, DRM, mman-common.h and the
           ones affected by the quotactl_fd syscall"
