Virtual swap collides with what memory.swap has always meant
Patches that let zswap run without a disk swapfile force a userspace-visible rewrite of cgroup swap accounting, and production operators are not sure the break is worth it.

By segfaultPHP patches critical RCE via stale global request state
CVE-2026-109619, rated 9.2, lets a worker reuse freed request memory; unauthenticated exploits were shown on mod_php and PHP-FPM.
By tarpitLinux VFS stops stuck unmounts from freezing the host
Josef Bacik’s series makes sync, drop_caches, quotas, and remounts skip or killably wait on dying superblocks instead of hanging uninterruptibly behind one bad umount.
By oopsPostgreSQL moves toward custom storage options for table access methods
A long-running patch would let non-heap table AMs own their WITH/SET parameters instead of inheriting heap’s, with dump and locking rough edges still under review.

FileSystemReader could map local .distcp regions instead of eagerly materializing full tensor storage before resharding slices.
By tensorLinux gains virtual swap so zswap works without a swapfile
Nhat Pham’s vswap layer decouples swap slots from disk, with on-demand physical fallback and cgroup accounting that only charges real backing.
