The kernel's slab allocator plays a critical role in providing small objects as needed and its performance and reliability are essential for the system's overall functioning. Two sessions at the Linux Storage, Filesystem, Memory-Management, and BPF Summit discussed current work on the slab allocator, including new features like sheaves and safe allocation functions that can be called in any context.  
The kernel's slab allocator is charged with providing small objects on
demand; its performance and reliability are crucial for the functioning of
the system as a whole.  At the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit, two adjacent sessions in the
memory-management track dug into current work on the slab allocator.  The
first focused on the new sheaves feature, while the second discussed a set
of allocation functions that are safe to call in any context.
