Hi Ross, can you take at my (fully working, but not fully cleaned up) version of the iomap based DAX code here:
http://git.infradead.org/users/hch/vfs.git/shortlog/refs/heads/iomap-dax By using iomap we don't even have the size hole problem and totally get out of the reverse-engineer what buffer_heads are trying to tell us business. It also gets rid of the other warts of the DAX path due to pretending to be like direct I/O, so this might be a better way forward also for ext2/4. _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
