Date: Sat, 18 Apr 2015 14:03:02 -0600 From: Jens Axboe <axboe@...com> To: <axboe@...nel.dk>, <linux-kernel@...r.kernel.org>, <linux-fsdevel@...r.kernel.org> CC: <ming.l@....samsung.com>, <adilger@...ger.c>, <david@...morbit.com> Subject: [PATCH v2] Support for write stream IDs Hi, v2 of this posting. Changes since v1: - Rebased on top of current master. - Fix EINVAL -> -EINVAL typo. - Cleanup up BIO_STREAM_OFFSET definition. - Pack i_streamid and f_streamid better into struct file and struct inode. - Add a separate per-file hint, FADV_FILE_STREAMID. This only sets the write stream on the file, not the inode. FADV_STREAMID sets the hint both in the file and the inode. block/bio.c | 2 ++ block/blk-core.c | 3 +++ fs/btrfs/extent_io.c | 1 + fs/btrfs/inode.c | 1 + fs/buffer.c | 4 ++-- fs/direct-io.c | 4 ++++ fs/ext4/page-io.c | 1 + fs/inode.c | 1 + fs/mpage.c | 1 + fs/open.c | 1 + fs/xfs/xfs_aops.c | 1 + include/linux/blk_types.h | 28 +++++++++++++++++++++++++++- include/linux/fs.h | 22 ++++++++++++++++++++++ include/uapi/linux/fadvise.h | 3 +++ mm/fadvise.c | 25 +++++++++++++++++++++++++ 15 files changed, 95 insertions(+), 3 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
