Hi Linus, The following changes since commit 84df9525b0c27f3ebc2ebb1864fa62a97fdedb7d: Linux 4.19 (2018-10-22 07:37:37 +0100) are available in the Git repository at: https://github.com/ceph/ceph-client.git tags/ceph-for-4.20-rc1 for you to fetch changes up to ea4cdc548e5e74a529cdd1aea885d74b4aa8f1b3: ceph: new mount option to disable usage of copy-from op (2018-10-22 10:28:24 +0200) ---------------------------------------------------------------- The highlights are: - a series that fixes some old memory allocation issues in libceph (myself). We no longer allocate memory in places where allocation failures cannot be handled and BUG when the allocation fails. - support for copy_file_range() syscall (Luis Henriques). If size and alignment conditions are met, it leverages RADOS copy-from operation. Otherwise, a local copy is performed. - a patch that reduces memory requirement of ceph_sync_read() from the size of the entire read to the size of one object (Zheng Yan). - fallocate() syscall is now restricted to FALLOC_FL_PUNCH_HOLE (Luis Henriques) ---------------------------------------------------------------- Chengguang Xu (3): ceph: reset cap hold timeout only for requeued inode rbd: add __init/__exit annotations ceph: check snap first in ceph_set_acl() Ilya Dryomov (12): libceph: bump CEPH_MSG_MAX_DATA_LEN libceph: osd_req_op_cls_init() doesn't need to take opcode libceph: introduce ceph_pagelist_alloc() libceph: don't consume a ref on pagelist in ceph_msg_data_add_pagelist() libceph: no need to call osd_req_opcode_valid() in osd_req_encode_op() ceph: num_ops is off by one in ceph_aio_retry_work() libceph: enable fallback to ceph_msg_new() in ceph_msgpool_get() libceph: assign cookies in linger_submit() libceph: introduce alloc_watch_request() libceph, rbd, ceph: move ceph_osdc_alloc_messages() calls libceph: preallocate message data items libceph: check reply num_data_items in setup_request_data() Luis Henriques (5): ceph: only allow punch hole mode in fallocate ceph: add non-blocking parameter to ceph_try_get_caps() libceph: support the RADOS copy-from operation ceph: support copy_file_range file operation ceph: new mount option to disable usage of copy-from op Xuehan Xu (1): ceph: set timeout conditionally in __cap_delay_requeue Yan, Zheng (4): Revert "ceph: fix dentry leak in splice_dentry()" ceph: fix dentry leak in ceph_readdir_prepopulate ceph: check if LOOKUPNAME request was aborted when filling trace ceph: refactor ceph_sync_read() Documentation/filesystems/ceph.txt | 5 + drivers/block/rbd.c | 28 +- fs/ceph/acl.c | 13 +- fs/ceph/addr.c | 2 +- fs/ceph/caps.c | 21 +- fs/ceph/file.c | 573 +++++++++++++++++++++++++++---------- fs/ceph/inode.c | 13 +- fs/ceph/mds_client.c | 9 +- fs/ceph/super.c | 13 + fs/ceph/super.h | 3 +- fs/ceph/xattr.c | 3 +- include/linux/ceph/libceph.h | 8 +- include/linux/ceph/messenger.h | 24 +- include/linux/ceph/msgpool.h | 11 +- include/linux/ceph/osd_client.h | 22 +- include/linux/ceph/pagelist.h | 11 +- include/linux/ceph/rados.h | 28 ++ net/ceph/messenger.c | 107 +++---- net/ceph/msgpool.c | 27 +- net/ceph/osd_client.c | 363 +++++++++++++++++------ net/ceph/pagelist.c | 20 ++ 21 files changed, 900 insertions(+), 404 deletions(-)
