Hi Seth -- Per offline communication, I'd like to see this delayed for three reasons: 1) I've completely rewritten zcache and will post the rewrite soon. The redesigned code fixes many of the weaknesses in zcache that makes it (IMHO) unsuitable for an enterprise distro. (Some of these previously discussed in linux-mm [1].) 2) zcache is truly mm (memory management) code and the fact that it is in drivers at all was purely for logistical reasons (e.g. the only in-tree "staging" is in the drivers directory). My rewrite promotes it to (a subdirectory of) mm where IMHO it belongs. 3) Ramster heavily duplicates code from zcache. My rewrite resolves this. My soon-to-be-post also places the re-factored ramster in mm, though with some minor work zcache could go in mm and ramster could stay in staging. Let's have this discussion, but unless the community decides otherwise, please consider this a NACK. Thanks, Dan [1] http://marc.info/?t=133886706700002&r=1&w=2 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
