msync() does a strange thing. Essentially: vma = find_vma(); for ( ; ; ) { if (!vma) return -ENOMEM; ... vma = vma->vm_next; } so an msync() request which starts within or before a valid VMA and which ends within or beyond the final VMA will incorrectly return -ENOMEM. Fix. Cc: Hugh Dickins <[email protected]> Cc: Nick Piggin <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
