I can't see where was it defined for arm64 after it looks like Andrew has deleted the above chunk. Thus, we have a warning using this .config: https://cailca.coding.net/public/linux/mm/git/files/master/arm64.config <stdin>:1539:2: warning: #warning syscall memfd_secret not implemented [-Wcpp]I was under the impression that Andrew only removed the #ifdef... Andrew, can you please restore syscall definition for memfd_secret() in include/uapi/asm-generic/unistd.h?
urgh, OK, that seems to have got lost in the (moderate amount of) conflict resolution).
