Subject: [36/37] Large blocksize support for ext2
Date: Wed, 20 Jun 2007 11:29:43 -0700 [thread overview]
Message-ID: <20070620183014.438784820@sgi.com> (raw)
In-Reply-To: 20070620182907.506775016@sgi.com
[-- Attachment #1: vps_filesystem_ext2 --]

This adds support for a block size of up to 64k on any platform.
It enables the mounting filesystems that have a larger blocksize
than the page size.
F.e. the following is possible on x86_64 and i386 that have only a 4k page
size.
mke2fs -b 16384 /dev/hdd2 <Ignore warning about too large block size>
mount /dev/hdd2 /media
ls -l /media
.... Do more things with the volume that uses a 16k page cache size on
a 4k page sized platform..
Hmmm... Actually there is nothing additional to be done after the earlier
cleanup of the macros. So just modify copyright.
