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.
