From: Mike Rapoport <redacted> Hi, This is an implementation of "secret" mappings backed by a file descriptor. I've dropped the boot time reservation patch for now as it is not strictly required for the basic usage and can be easily added later either with or without CMA.
On powerpc: https://gitlab.com/cailca/linux-mm/-/blob/master/powerpc.config There is a compiling warning from the today's linux-next: <stdin>:1532:2: warning: #warning syscall memfd_secret not implemented [-Wcpp]
