MINSIGSTKSZ

MINSIGSTKSZ is a constant defined in the Linux kernel, specifically in the signal handling subsystem. It represents the minimum stack size required for a signal handler to execute safely. The value of MINSIGSTKSZ is typically set to 2048 bytes, which is the smallest stack size that the kernel will allocate for a signal handler. This ensures that the signal handler has enough space to execute its code without causing a stack overflow or other memory-related issues. The constant is used in the kernel's signal handling functions to allocate the appropriate stack space for signal handlers, ensuring that they can run correctly and reliably. The value of MINSIGSTKSZ can be adjusted by kernel developers if necessary, but it is generally recommended to keep it at the default value to maintain compatibility and stability.
