save the patch:
cut the text, the first line should be:
- - --- linux-akpm/fs/buffer.c~sync_fs    Thu Dec  5 21:33:56 2002

the last line is the - just before the signature.  Make sure you don't
wrap any lines cutting and pasting between the message and the patch file.

assuming your kernel source is /usr/src/linux, save the patch in /usr/src
as ext3.patch and cd linux

I suggest you "dry-run" the patch first (test it):

patch -p1 --dry-run < ../ext3.patch

If you get no failures (you will if you put the XFS patch on), then remove
the --dry-run and go again.

If you decide you don't want the patch anymore, just do:

patch -p1 -R < ../ext3.patch

and all will be reversed.


Hope I didn't obfuscate things too much. ;-)

Next lesson:  creating unified diff patches.
