A re-write and merge of the Squashfs metadata and fragment cache code has been finished (it is in the Squashfs CVS tree). The original implementation had a number of performance issues which I wanted to address before resubmission. The major work of course is the move to a little endian layout without any bit fields in the structures to make it easier to swap member fields on big-endian architectures. I'm currently working on this on a non-CVS branch. Most of the work till now has been without any attempt to retain backwards compatibility with the current 3.3 little-endian filesystem layout. After your private email regarding retaining backwards compatibility I will look again at this issue, it may well be that I will abandon my current layout changes that I have so far made. I have taken time off work to work on the necessary mainline changes full time (unpaid unfortunately, so I need to look for another job soon). Hopefully this will mean I will make better progress than I have been able to in the last couple of years. Phillip
