Re: [PATCH v2 2/2] elf: Support THP segment load with madvise enabled THP

headline

Support THP segment load with madvise enabled THP

tldr

This patch enables THP segment loading when THP is enabled with madvise in the kernel.

stakes

Allows applications to take advantage of THP even when the kernel is configured to use madvise mode, potentially improving performance.

sentiment_rationale

The patch addresses a limitation in THP support and builds upon previous work. The discussion suggests ongoing refinement.

technical_tradeoffs

• • Requires changes to the dynamic linker to handle madvise-based THP.
• • Adds complexity to the ELF loading process.
