> vfs: add f_op->pre_mmap() We've been through these pre-mmap games a few times, and always rejected them, why is this any different? > vfs: export vfs_dedupe_file_range_one() to modules Please use EXPORT_SYMBOL_GPL for all these crazy low-level exports. To be homest I'd really like to see the whole thing as a patch series instead of a pull request. Very little seems to have gotten any reviewed-by tags which makes me very suspicious.
