SubjectRe: [PATCH 1/9] Squashfs: move zlib decompression wrapper code into a separate file

Yes, but it isn't in mainline, and OpenWRT don't appear to have tried to submit
it. IMHO the major problem with their patch is it uses a second private copy
of lzma, rather than being a wrapper around the pre-existing lzma implementation.
I don't think it's going to be easy to get a second lzma implementation accepted
into mainline, when it took so long to get one accepted. I have nothing against
the cryptoapi, but it doesn't seem likely to be getting lzma support anytime soon.

As I previously said my aim is to use the pre-existing lzma implementation. Unless
it is stupendously bad (which it isn't), that seems to be the quickest, easiest and
best way to get lzma support into Squashfs.
