Will do.
There are 3 copies of this function which are slightly different:
- arch/s390/mm/mmap.c (checks rlim_stack)
- arch/x86/mm/mmap.c (does not check rlim_stack)
- mm/util.c (checks rlim_stack if CONFIG_STACK_GROWSUP)
I wonder if it would be best to merge all 3 into one? The one in
mm/util.c seems to be generic enough. Export it and have its prototype
in linux/mm.h?
