Issue Description:

Certain 8.X versions of MongoDB will exit during startup when running on Linux kernel versions 6.19 and later.

This behavior was introduced to mitigate the impact of userspace breaking changes in the linux kernel which impacted the tcmalloc memory allocator. These changes negatively impacted MongoDB's stability and correctness, and caused MongoDB to crash after ~60 seconds.

Linux kernel versions 7.0.14+ and 7.1.0+ (inclusive) restore previous userspace behavior.

This ticket (SERVER-125742) removes this graceful exit on Linux kernel versions containing the kernel fixes referenced above. This change will be released in the coming weeks in versions 8.0.30, 8.3.9, and 9.X+.

Please see the table below for the expected behavior of different versions of MongoDB on different versions of the Linux kernel.

Compatibility Matrix:

• Fully supported
• Impacted - see comment

MongoDB Version	Linux Kernel < 6.19	Linux Kernel 6.19 - 7.0.13	Linux Kernel 7.0.14+ / 7.1.0+ (inclusive)
7.0 (All versions)
8.0.0 - 8.0.20		DO NOT USE - MongoDB crashes after ~60 seconds, potential corruption
8.0.21 - 8.0.29 8.3.0 - 8.3.8		MongoDB exits during startup	MongoDB exits during startup
8.0.30+ 8.3.9+ 9.0 (All versions)		MongoDB exits during startup

Root cause:

Changes to rseq behavior in the Linux Kernel impact the tcmalloc memory allocator, resulting in instability in MongoDB.

Fix or Remediations:

We recommend using the latest maintenance release of MongoDB for your respective major version.
