Hi all, DMAPI (apparently) was some sort of data management API that at some point in the distant past could be used to implement a hierarchal storage manager (HSM) using XFS. This sounds kind of neat because you can dynamically page in (or evict out) parts of files to even cheaper storage, but it has never been implemented in the upstream XFS driver or any other filesystem. Get rid of these tests. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=remove-dmapi --- .gitignore | 79 - Makefile | 5
