However, I did move it back to the core series for v8, it's this one: https://git.kernel.dk/cgit/linux/commit/?h=buffered-uncached.10&id=e4b7e8f693caf84021424ebafa139f38c5599db3 to avoid having a core dependency for the patches adding support to iomap and xfs/btrfs. I'll send out a new version with just slight tweaks today. So far it has the following changelog: - Rename filemap_uncached_read() to filemap_end_dropbehind_read() - Rename folio_end_dropbehind() to folio_end_dropbehind_write() - Make the "mm: add FGP_DONTCACHE folio creation flag" patch part of the base patches series, to avoid dependencies with btrfs/xfs/iomap - Remove now dead IOMAP_F_DONTCACHE define and setting on xfs/iomap where moving this patch back to teh core series is one of the entries. -- Jens Axboe
