Squashfs: Make ZLIB compression support optional

2011-07-22T02:01:28+00:00

Squashfs now supports XZ and LZO compression in addition to ZLIB.
As such it no longer makes sense to always include ZLIB support.
In particular embedded systems may only use LZO or XZ compression, and
the ability to exclude ZLIB support will reduce kernel size.

email to one that will continue working.

Squashfs: extend decompressor framework to handle compression options

2011-02-28T18:21:59+00:00

Extend decompressor framework to handle compression options stored in
the filesystem.  These options can be used by the relevant decompressor
at initialisation time to over-ride defaults.

The presence of compression options in the filesystem is indicated by
the COMP_OPT filesystem flag.  If present the data is read from the
filesystem and passed to the decompressor init function.  The decompressor
init function signature has been extended to take this data.

Also update the init function signature in the glib, lzo and xz
decompressor wrappers.

in decompressor.c

Squashfs: move squashfs_i() definition from squashfs.h

2011-01-13T21:24:15+00:00

Move squashfs_i() definition out of squashfs.h, this eliminates
the need to #include squashfs_fs_i.h from numerous files.

Squashfs: add decompressor entries for lzma and lzo

2010-01-20T21:47:48+00:00

Add knowledge of lzma/lzo compression formats to the decompressor
framework.  For now these are added as unsupported.  Without
these entries lzma/lzo compressed filesystems will be flagged as
having unknown compression which is undesirable.

Squashfs: add a decompressor framework

2010-01-20T21:47:47+00:00

This adds a decompressor framework which allows multiple compression
algorithms to be cleanly supported.

Also update zlib wrapper and other code to use the new framework.
