v5.29.2

Security

• zstd-sys 2.1.2, for RUSTSEC-2026-0410, which affects only the WebAssembly
  viewer. 6.0 has it through the zstd 0.14 move (#1563), which needs parquet
  60; on 5.x it is taken directly in #1595. RUSTSEC-2026-0391,
  RUSTSEC-2026-0398 and RUSTSEC-2026-0403 (zstd, zstd-safe) remain on 5.x.

Fixed

• memory_pagecache loads on 6.18 and later kernels. From 6.18
  folio->flags is a memdesc_flags_t struct, so the CO-RE relocation for
  the integer read of it failed, the verifier rejected the fill and eviction
  programs, and the sampler failed with Invalid argument (os error 22). The
  flags word is now read from flags.f where the kernel wraps it.
  Backported from 6.0 (#1590) in #1595.
