Linux Kernel Add PR_SET_VMA support to Linux Kernel
About the Organization
PR_SET_VMA mechanism is used heavily in Android for naming memory regions. It is passed to the prctl(2) system call along with the range of addresses to be named. The name appears in /proc/pid/maps and can be used to identify memory regions for debugging and accounting purposes. The patch has been carried in the Android tree for several years. The patch needs to be adapted to mainline, improved and finally upstreamed. This project will give the mentee a good understanding of virtual memory area structures in the Linux kernel as the name for the memory region is stored in these structures and there are various cases where a memory map needs to be split or merged depending on its name compared to its immediate neighbors.
