Subject: [PATCH 001/001] hostfs: set maximum filesize in superblock for proper LFS support
Date: Mon, 29 Jun 2009 23:59:01 +0200 [thread overview]
Message-ID: <200906292359.01834.wolfgang@illmeyer.com> (raw)
From: Wolfgang Illmeyer <wolfgang@illmeyer.com>
Maximum file size for hostfs mounts defaults to 2GB, so bigger files cannot be
read/written through hostfs. This patch initializes the maximum file size to
MAX_LFS_SIZE.

This patch applies against linux-2.6.30. It fixes
http://bugzilla.kernel.org/show_bug.cgi?id=13531
It is a revamped version of the patch I attached to the bug, using additional
input from Andrew Morton (thanks). This is my first patch for the kernel, I
hope I didn't break too many rules ;)
For any feedback from the mailing list please add me to "To" or CC me - I'm
not on the list.
