Hi Dan,
I just noticed that we now do a fs_dax_get_by_host in every iomap_begin call for DAX. This function iterates a list, does a string compared and igrab. I really think we need to cache this in the superblock (possible even the fs superblock) similar to what we do for the block device. _______________________________________________ Linux-nvdimm mailing list [email protected] https://lists.01.org/mailman/listinfo/linux-nvdimm
