From: Keith Busch <kbusch@xxxxxxxxxx> Nothing's changed from intended v6. This just fixes up the directory for the mailed patch set. Changes from v5: Merged up to latest block for-next tree Fixed up the io_uring read/write fixed prep to not set do_import, and actually use the issue_flags when importing the buffer node (Pavel, Caleb). Used unambigious names for the read/write permissions of registered kernel vectors, defined them using their symbolic names instead of literals, and added a BUILD_BUG_ON to ensure the flags fits in the type (Ming, Pavel). Limit the io cache size to 64 elements (Pavel). Enforce unpriveledged ublk dev can't use zero copy (Ming). Various cleanups. Keith Busch (5): io_uring/rw: move fixed buffer import to issue path io_uring: add support for kernel registered bvecs ublk: zc register/unregister bvec io_uring: add abstraction for buf_table rsrc data io_uring: cache nodes and mapped buffers Xinyu Zhang (1): nvme: map uring_cmd data even if address is 0 drivers/block/ublk_drv.c | 119 +++++++++----- drivers/nvme/host/ioctl.c | 2 +- include/linux/io_uring/cmd.h | 7 + include/linux/io_uring_types.h | 24 +-- include/uapi/linux/ublk_cmd.h | 4 + io_uring/fdinfo.c | 8 +- io_uring/filetable.c | 2 +- io_uring/io_uring.c | 3 + io_uring/nop.c | 2 +- io_uring/opdef.c | 4 +- io_uring/register.c | 2 +- io_uring/rsrc.c | 280 ++++++++++++++++++++++++++------- io_uring/rsrc.h | 10 +- io_uring/rw.c | 39 +++-- io_uring/rw.h | 2 + 15 files changed, 389 insertions(+), 119 deletions(-) -- 2.43.5
