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.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins1-5/+8
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: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by: Hugh Dickins <[email protected]> Reviewed-by: Shakeel Butt <[email protected]> Acked-by: Kirill A.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux 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" * tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (29 commits) perf test: Add free() calls for scandir() returned dirent entries libperf: Add tests for perf_evlist__set_leader() libperf: Remove BUG_ON() from library code in get_group_fd() libperf: Add group support to perf_evsel__open() perf tools: Fix pattern matching for same substring in different PMU type perf record: Add a dummy event on hybrid systems to collect metadata records perf stat: Add Topdown metrics L2 events as default events libperf: Adopt evlist__set_leader() from tools/perf as perf_evlist__set_leader() libperf: Move 'nr_groups' from tools/perf to evlist::nr_groups libperf: Move 'leader' from tools/perf to perf_evsel::leader libperf: Move 'idx' from tools/perf to perf_evsel::idx libperf: Change tests to single static and shared binaries perf intel-pt: Add a config for max loops without consuming a packet perf stat: Disable the NMI watchdog message on hybrid perf vendor events power10: Adds 24x7 nest metric events for power10 platform perf script python: Fix buffer size to report iregs in perf script perf trace: Fix the perf trace link location perf top: Fix overflow in elf_sec__is_text() perf annotate: Fix 's' on source line when disasm is empty perf probe: Do not show @plt function by default ...

2021-07-10mm/page_alloc: Revert pahole zero-sized workaroundMel Gorman2-14/+0
Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock") folded in a workaround patch for pahole that was unable to deal with zero-sized percpu structures. A superior workaround is achieved with commit a0b8200d06ad ("kbuild: skip per-CPU BTF generation for pahole v1.18-v1.21"). This patch reverts the dummy field and the pahole version check.
