From e4eb1ff61b323d6141614e5458a1f53c7046ff8e Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 20 Apr 2012 15:35:40 -0700 Subject: VM: add "vm_brk()" helper function It does the same thing as "do_brk()", except it handles the VM locking too. It turns out that all external callers want that anyway, so we can make do_brk() static to just mm/mmap.c while at it.
