From: Omar Sandoval <osandov@fb.com> This series adds support for sending compressed data via Btrfs send and btrfs-progs support for sending/receiving compressed data and writing it with BTRFS_IOC_ENCODED_WRITE, which was previously merged into misc-next. See the previous posting for more details and benchmarks [1]. Patches 1 and 2 are cleanups for Btrfs send. Patches 3-5 prepare some protocol changes for send stream v2. Patch 6 implements compressed send. Patch 7 enables send stream v2 and compressed send in the send ioctl when requested. Changes since v13 [2]: - Rebased on latest misc-next branch. - Dropped ioctl patches which are already in misc-next. 1: https://lore.kernel.org/linux-btrfs/cover.1615922753.git.osandov@fb.com/ 2: https://lore.kernel.org/linux-btrfs/cover.1644519257.git.osandov@fb.com/ Omar Sandoval (7): btrfs: send: remove unused send_ctx::{total,cmd}_send_size btrfs: send: explicitly number commands and attributes btrfs: add send stream v2 definitions btrfs: send: write larger chunks when using stream v2 btrfs: send: allocate send buffer with alloc_page() and vmap() for v2 btrfs: send: send compressed extents with encoded writes btrfs: send: enable support for stream v2 and compressed writes fs/btrfs/ctree.h | 6 + fs/btrfs/inode.c | 13 +- fs/btrfs/send.c | 324 +++++++++++++++++++++++++++++++++---- fs/btrfs/send.h | 142 +++++++++------- include/uapi/linux/btrfs.h | 10 +- 5 files changed, 395 insertions(+), 100 deletions(-) The btrfs-progs patches were written by Boris Burkov with some updates from me. Patches 1-4 are preparation. Patch 5 implements encoded writes. Patch 6 implements the fallback to decompressing. Patches 7 and 8 implement the other commands. Patch 9 adds the new `btrfs send` options. Patch 10 adds a test case. Changes since v13: - Rebased on latest devel branch. - Updated the btrfs_ioctl_encoded_io_args definition to the version that was merged into misc-next.
