Linux Kernel Memory Map . Understanding the Linux Kernel [Detailed Guide] Linux Magazine The recommended usage of the flags is described at Memory Allocation Guide. Linux memory management subsystem is responsible, as the name implies, for managing the memory in the system
Memory mapping — The Linux Kernel documentation from linux-kernel-labs.github.io
The direct mapping covers all memory in the system up to the highest memory address (this means in some cases it can also include PCI memory holes). MAP_SYNC (since Linux 4.15) This flag is available only with the MAP_SHARED_VALIDATE mapping type; mappings of type MAP_SHARED will silently ignore this flag
