At the time, xfstests was going through maintainer issues - SGI was dropping the ball, and I didn't start to pick stuff up until mid january 2014. http://oss.sgi.com/archives/xfs/2014-01/msg00283.html "Note that I didn't pull in the tmpfs support patch series this time around as I'm not sure the discussions ever came to a conclusion before xmas/new year/LCA intervened. That will need to be picked up again..." And there was no followup reposts of the patchset, so it's not gone anywhere since. > As there are no archives of fstests m-l I couldn't find why his > patches weren't applied so apologise if this is innapropriate but > I rebased his patch upon current xfstests code: Tell me about it. If anyone knows the magic incantation to get the usual mailing list archive sites to answer a simple "can you archive this list" request, let me know, because I've tried repeatedly since this list was created and haven't had a single reply from any of them. FYI, when send patches with comments like this, the comments should be below the first "---" divider so that utilities like git am, patch, etc strip the comments away. In this case, they strip this: > --- > > Some filesystems do not support O_DIRECT.
