Hi all, Today's linux-next merge of the fuse tree got a conflict in: fs/fuse/file.c between commit: 933a3752babc ("fuse: fix the ->direct_IO() treatment of iov_iter") from Linus' tree and commit: fcee216beb9c ("fuse: split fuse_mount off of fuse_conn") from the fuse tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc fs/fuse/file.c index 43c165e796da,53d4dd1ab992..000000000000 --- a/fs/fuse/file.c +++ b/fs/fuse/file.c @@@ -3120,17 -3156,10 +3146,18 @@@ fuse_direct_IO(struct kiocb *iocb, stru * By default, we want to optimize all I/Os with async request * submission to the client filesystem if supported. */ - io->async = ff->fc->async_dio; - io->async = async_dio; ++ io->async = ff->fm->fc->async_dio; io->iocb = iocb; io->blocking = is_sync_kiocb(iocb); + /* optimization for short read */ + if (io->async && !io->write && offset + count > i_size) { - iov_iter_truncate(iter, fuse_round_up(ff->fc, i_size - offset)); ++ iov_iter_truncate(iter, fuse_round_up(ff->fm->fc, ++ i_size - offset)); + shortened = count - iov_iter_count(iter); + count -= shortened; + } + /* * We cannot asynchronously extend the size of a file. * In such case the aio will behave exactly like sync io.
