BTRFS: error (device vdc: state A) in create_pending_snapshot:1875: errno=-2 No such entry
BTRFS info (device vdc: state EA): forced readonly
BTRFS warning (device vdc: state EA): Skipping commit of aborted transaction.
BTRFS: error (device vdc: state EA) in cleanup_transaction:2055: errno=-2 No such entry
This happens because create_pending_snapshot() initializes the new root
item as a copy of the source root item. This includes the refs field,
which is 0 for a deleted subvolume. The call to btrfs_insert_root()
therefore inserts a root with refs == 0. btrfs_get_new_fs_root() then
finds the root and returns -ENOENT if refs == 0, which causes
create_pending_snapshot() to abort.
Fix it by checking the source root's refs before attempting the
snapshot, but after locking subvol_sem to avoid racing with deletion.

CVE: NA
Reference: https://lore.kernel.org/all/20240327090835.3232629-1-zhangpeng362@huawei.co…
--------------------------------
When vma->vm_userfaultfd_ctx.ctx is NULL, vma->vm_flags should have
cleared __VM_UFFD_FLAGS. Therefore, there is no need to down_write or
clear the flag, which will affect fork performance. Fix this by
returning early if octx is NULL in dup_userfaultfd().
By applying this patch we can get a 1.3% performance improvement for
lmbench fork_prot. Results are as follows:
base early return
Process fork+exit: 419.1106 413.4804

From: ZhangPeng <zhangpeng362(a)huawei.com>
This patch set includes two patch sets: Mitigate a vmap lock contention
and mm/vmalloc: lock contention optimization under multi-threading.
In high-concurrency scenarios such as the "/test_vmalloc.sh
run_test_mask=7 nr_threads=64" scenario, the performance is improved by
more than 10x. The run time was reduced from 18m45.268s to 1m45.066s.
Changelog:
v2->v3:
- Fix commit format warning
v1->v2:
- Remove 2 maillist inclusion patches
- Merge patch 21 to resolve the conflict in patch 16
Alexei Starovoitov (3):
mm: Enforce VM_IOREMAP flag and range in ioremap_page_range.
mm: Introduce VM_SPARSE kind and vm_area_[un]map_pages().
mm: Introduce vmap_page_range() to map pages in PCI address space
Baoquan He (2):
mm/vmalloc: fix the unchecked dereference warning in vread_iter()
mm/vmalloc: remove vmap_area_list
Uladzislau Rezki (Sony) (13):
mm: vmalloc: add va_alloc() helper
mm: vmalloc: rename adjust_va_to_fit_type() function
mm: vmalloc: move vmap_init_free_space() down in vmalloc.c
mm: vmalloc: remove global vmap_area_root rb-tree
mm: vmalloc: remove global purge_vmap_area_root rb-tree
mm: vmalloc: offload free_vmap_area_lock lock
mm: vmalloc: add a scan area of VA only once
mm: vmalloc: support multiple nodes in vread_iter
mm: vmalloc: support multiple nodes in vmallocinfo
mm: vmalloc: set nr_nodes based on CPUs in a system
mm: vmalloc: add a shrinker to drain vmap pools
mm: vmalloc: improve description of vmap node layer
mm: vmalloc: refactor vmalloc_dump_obj() function
