Hi all, Today's linux-next merge of the akpm-current tree got a conflict in: fs/btrfs/file.c between commit: 0225a20db6d8 ("btrfs: Prevent nowait or async read from doing sync IO") from the btrfs tree and commit: ddcd14c48a30 ("mm/filemap: rename generic_file_buffered_read to filemap_read") from the akpm-current 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/btrfs/file.c index 5282f456c99c,898ef7b792b7..000000000000 --- a/fs/btrfs/file.c +++ b/fs/btrfs/file.c @@@ -3629,18 -3639,7 +3629,18 @@@ static ssize_t btrfs_file_read_iter(str return ret; } - return filemap_read(iocb, to, ret); + if (iocb->ki_flags & IOCB_NOWAIT) + iocb->ki_flags |= IOCB_NOIO; + - ret = generic_file_buffered_read(iocb, to, ret); ++ ret = filemap_read(iocb, to, ret); + + if (iocb->ki_flags & IOCB_NOWAIT) { + iocb->ki_flags &= ~IOCB_NOIO; + if (ret == 0) + ret = -EAGAIN; + } + + return ret; } const struct file_operations btrfs_file_operations = {
