Please, please, no. This patch is of course correct,

The following patch series adds LZO compression support to the kernel
and exposes it in a variety of places (jffs2, crypto).
This is particularly useful for jffs2 where significant boot time
speedups (~10%) and file read speed improvements (~40%) are seen when
its used with only a slight drop in
Add LZO1X compression/decompression support to the kernel.
This is based on the standard userspace lzo library, particularly
minilzo with the headers much trimmed down and simplified for kernel
use. Its structured so that it should still diff with the userspace
version for ease of future
Add LZO1X compression/decompression support to jffs2.
LZO's interface doesn't entirely match that required by jffs2 so a
buffer and memcpy is unavoidable.

Add a favourlzo compression mode to jffs2 which tries to
optimise by size but gives lzo an advantage when comparing sizes.
This means the faster lzo algorithm can be preferred when there
isn't much difference in compressed size (the exact threshold can
be changed).

Allow selection of the compression mode for jffs2 via a sysfs
attribute. This establishes a sysfs presence for jffs2 through
which other compression options could easily be exported too.

Add LZO1X compression support to the crypto interface, including
a couple of tests.
Also convert test_deflate into a more generic test_compress() and
avoid duplicating the data for compression and decompression tests
since this can always work both ways in the compression case.

There is actually a file-system subsys - look up for fs_subsys. It is
declared at fs/namespace.c.

fair enough. Please rename it to FIX_PARAVIRT_BOOTUP - you can still
rely on it being available later on too, but we'd like to give everyone
the right fundamental idea about this: it's meant to be a limited,

Will do.

It is true that debug registers are inherited by fork and clone.
I am 99% sure that this was never specifically intended, but it
has been this way for a long time (since 2.4 at least). It's an
implicit consequence of the do_fork implementation style, which
does a blind copy of the whole
