2009-02-24mkfs.jffs2: fix lzo usage on 64bit systemsSebastian Andrzej Siewior
the compress size parameter in lzo is defined in the header file as lzo_uint. This looks very much like uint32_t, I know, but is defined as unsigned long. So on 64bit LE systems we zero some bytes near by and on BE systems we get a size of zero.

2008-04-17compr_lzo.c: allocate enough memory for lzo compressor.Riku Voipio
This is the same bug as in kernel, pointed out the LZO author (Markus Oberhumer): http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f2a11b158a24301e9158e9c873fa88e5eb775486 Signed-off-by: Riku Voipio <riku.voipio@iki.fi> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-08-03Disable LZO compression by defaultJosh Boyer
When the recent LZO compression support went into mtd-utils recently, it was enabled by default. This means that mkfs.jffs2 will default to creating images with lzo compression as the default. Older kernels cannot decompress such images, so lzo should be disabled by default. The patch below fixes this. To enable lzo compression from now on, simply pass '-X lzo' as an option to mkfs.jffs2.

2007-07-23Use lzo2 librariesJosh Boyer
Switch to using the more common lzo2 libraries for LZO compression. They should still work with the lzo1x interfaces. Signed-off-by: Josh Boyer <jwboyer@gmail.com>
2007-07-23Add lzo support to mtd-utilsRichard Purdie
Add LZO support to mtd-utils to generate LZO compressed jffs2 images Unlike the kernel version, the standard lzo userspace library is used along with lzo1x_999_compress rather than the lzo1x_1_compress version since better compression ratios can be obtained (at no significant cost to decompression time).
