[ros-dev] Cache / Memory Manager / FileSystemDrivers

[Pierre SCHWEITZER]

Hi,
how far can we use it? It must be under Microsoft copyright. Moreover, it must be quite complete, so it would not be a rewrite, just an importation.

The WDK ships with a working windows 2003 fat driver... rewrite it based on that one.Best regards,

Live branch needs constant merging. Have a look at amd64 bringup

branch: most of commits are merges. That mm.patch is an ugly way of

keeping the branch always uptodate...



Anyway, I have made some fixes to the branch, so if someone wants to

test, I would need to commit my changes.



As for the fastfat, I think the problems is in synchronization

somewhere, not in a pool corruption, passing invalid parameters,

misusing Cc API, or anything like that - I fixed that already.



Another idea was to take ext2fsd by Matt Wu, which is supposed to

work, and convert it to a fat32/16/12 driver.
