Revision e4eb1ff61b323d6141614e5458a1f53c7046ff8e authored by Linus Torvalds on 20 April 2012, 22:35:40 UTC, committed by Linus Torvalds on 21 April 2012, 00:28:17 UTC
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
