2.6.1-rc1-tiny1 tree for small systems

From: Matt Mackall
Date: Fri Jan 02 2004 - 22:09:51 EST

This is the third release of the -tiny kernel tree. The aim of this
tree is to collect patches that reduce kernel disk and memory
footprint as well as tools for working on small systems. Target users
are things like embedded systems, small or legacy desktop folks, and

Latest release includes:
- sync against 2.6.1-rc1
- latest netdrvr patchkit
- SLOB allocator
- Andi Kleen's bloat-o-meter
- configurable tcpdiag, inetpeer, dnotify, ptrace, sysenter/vsyscall
- configurable X86 CPU feature detection
- ability to override arch CFLAGS from Kconfig
- optional uninlining of current and thread_info
- other minor tweaks

The big bit here is SLOB, which optionally replaces the SLAB allocator
and kmalloc wrappers with a traditional malloc arena and a SLAB
emulation layer. SLOB is less than a tenth the size of the SLAB code
and is considerably more space efficient with its allocations, but is
not as fast and may prove less resistant to long-term fragmentation.

Thanks to Andi Kleen, Magnus Naeslund, and various others for their
contributions and suggestions.

The patch can be found at:


Contributions and suggestions are encouraged. In particular, it would
be helpful if people with non-x86 hardware could take a stab at
extending some of the stuff that's currently only been done for X86 to
other architectures.
