Linux Kernel: Release Candidate Cleanup Sweep
The run-up to 7.3-rc4 pulled in a wide batch of subsystem fixes, with a recurring focus on data-corruption and overflow bugs in memory management, tracing, and boot parsing. Several fixes address long-standing bugs that only surface under specific, hard-to-hit conditions.

It's September 14th, and this is your Linux Kernel briefing on the fixes heading into 7.3-rc4.
The dominant pattern today is late-cycle hardening against data loss and integer overflow bugs, several of which have been latent for a long time. In commit 704340f, Dave Hansen's x86 pull fixes a THP bug where user-space data could silently vanish under memory pressure combined with MADV_FREE — a bug Hansen notes…
That overflow theme repeats in tracing and boot code. Vincent Donnefort's ring buffer remote fixes, commits d059d8b and 442ffa7, correct size calculations that undercounted pages needed for remote ring buffers and could silently overflow a 32-bit field, resulting in smaller-than-requested buffers. The bootconfig…
A second theme is locking and lifecycle correctness across subsystems. The tracing pull under commit 2209876 bundles over twenty fixes: user event fields being freed before their events are fully removed, a fork-time bug where ftrace could free a parent task's stack pointer, and a ring buffer wake-up path that…
Rounding out the sweep: perf fixes for PEBS re-entry and list corruption during event overflow, timer fixes for a broadcast device replacement race, and a…
