Message-Id: <1431984439-15008-1-git-send-email-joro@8bytes.org> Date: Mon, 18 May 2015 23:27:19 +0200 From: Joerg Roedel <joro@...tes.org> To: Tony Luck <tony.luck@...el.com>, Fenghua Yu <fenghua.yu@...el.com> Cc: linux-ia64@...r.kernel.org, linux-kernel@...r.kernel.org, Joerg Roedel <jroedel@...e.de> Subject: [PATCH] ia64: Return -ENOMEM in ia64_mmap_check() error case From: Joerg Roedel <jroedel@...e.de> The value -ENOMEM is the expected return code for mmap when the address range verification failes on a MAP_FIXED request, as stated in the specification: [ENOMEM] MAP_FIXED was specified, and the range [addr,addr+len) exceeds that allowed for the address space of a process; The ia64_mmap_check() function is part of that verification and should return -ENOMEM too.
