Hi I started to look into this old issue with mm subsystem and SGX, i.e. can we make SGX VMA's to merge together? This demonstrates the problem pretty well: https://lore.kernel.org/linux-sgx/884c7ea454cf2eb0ba2e95f7c25bd42018824f97.camel@xxxxxxxxxx/ It was result of brk() syscall being applied a few times.
