Subject: [PATCH] exec: allow > 2GB executables to run on 64-bit systems
Date: Wed, 05 Dec 2007 10:36:48 -0500 [thread overview]
Message-ID: <4756C590.9080301@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 342 bytes --]
When a executable that is greater than 2GB in size is attempted on a 64-bit
system on a file system that calls, or uses generic_file_open() as its
open handler, it fails with an EOVERFLOW erro. This patch adds a call
to force_o_largefile() call in open_exec(), as done in sys_open() and
sys_openat().
