+Subject: [PATCH] fs/exec.c: fix initial stack reservation
+
+803bf5ec259941936262d10ecc84511b76a20921 ("fs/exec.c: restrict initial
+stack space expansion to rlimit") attempts to limit the initial stack to
+20*PAGE_SIZE. Unfortunately, in attempting ensure the stack is not
+reduced in size, we ended up not changing the stack at all.
+
+This size reduction check is not necessary as the expand_stack call does
+this already.
+
+This caused a regression in UML resulting in most guest processes being
+killed.
