Subject: [35/36] Large blocksize support for ext2
Date: Tue, 28 Aug 2007 12:06:26 -0700 [thread overview]
Message-ID: <20070828190736.220951776@sgi.com> (raw)
In-Reply-To: <20070828190551.415127746@sgi.com>
[-- Attachment #1: 0035-Large-blocksize-support-for-ext2.patch --]
[-- Type: text/plain, Size: 1072 bytes --]
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.
