Jann Horn de70236fbe fs: take i_mutex during prepare_binprm for set[ug]id executables 
commit 8b01fc86b9 upstream.

This prevents a race between chown() and execve(), where chowning a
setuid-user binary to root would momentarily make the binary setuid
root.

This patch was mostly written by Linus Torvalds.
