But there was another case where we expand mappings hiding in plain sight: the automatic stack expansion. This fixes that case too. This one also found by Robert ÅšwiÄ™cki, using his nasty system call fuzzer tool. Good job. Reported-and-tested-by: Robert ÅšwiÄ™cki Cc: stable@kernel.org Signed-off-by: Linus Torvalds ìÈ
