The linux-tiny patchset is a series of patches against the 2.6 mainline Linux kernel to reduce its memory and disk footprint, as well as to add features to aid working on small systems. Target users are developers of embedded system and users of small or legacy machines such as 386s and handhelds.

Linux-tiny seems not to have been maintained after kernel version 2.6.14. I've made my own broken-out patch set for 220.127.116.11.
Original Announcements and e-mail
The original (Dec 11, 2003) announcement about the patchset, to the kernel mailing list, is available here:
Here are some other announcements from Matt Mackall to LKML:
Note that currently, the smallest kernel that is reported in this thread is 197K compressed.
A recent Linux-tiny patchset release is available here: Media:tiny-quilt-2.6.22-rc7-1.tar.gz
To apply the above patches, you need the referenced kernel (2.6.22-rc7) and quilt. Follow these steps:
- wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.tar.bz2
- tar -xjf linux-2.6.21.tar.bz2
- wget http://www.kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.22-rc7.bz2
- bunzip2 patch-2.6.22-rc7.bz2
- wget http://elinux.org/images/6/6d/Tiny-quilt-2.6.22-rc7-1.tar.gz
- cd linux-2.6.21
- patch -p1 <../patch-2.6.22-rc7
- tar -xzf ../Tiny-quilt-2.6.22-rc7-1.tar.gz
- quilt push -a
Here is a short shell script for making a tiny-quilt release: Media:release-tiny

Test Project and Results
The CELF System Size working group has worked extensively with the Linux-tiny patch set. There is a script to produce a report of size reductions for the individual patches in the patchset, and results from various vendors about their use of Linux-tiny. See Linux Tiny Test Project
