Hi Andrew, After merging the akpm-current tree, today's linux-next build (arm multi_v7_defconfig) failed like this: fs/binfmt_elf.c: In function 'load_elf_binary': fs/binfmt_elf.c:1140:7: error: 'elf_interpreter' undeclared (first use in this function); did you mean 'interpreter'? if (!elf_interpreter) ^~~~~~~~~~~~~~~ interpreter Caused by commit 3ebf0dd657ce ("fs/binfmt_elf.c: move brk out of mmap when doing direct loader exec") interacting with commit a34f642bccf1 ("fs/binfmt_elf.c: free PT_INTERP filename ASAP") I have applied the following patch for today.
