ceph: Remove osd_client deadcode

2025-04-03T19:35:32+00:00

osd_req_op_extent_osd_data_pagelist() was added in 2013 as part of
commit a4ce40a9a7c1 ("libceph: combine initializing and setting osd data")
but never used.

The last use of osd_req_op_cls_request_data_pagelist() was removed in
2017's commit ecd4a68a26a2 ("rbd: switch rbd_obj_method_sync() to
ceph_osdc_call()")

Remove them.

ceph: streamline request head structures in MDS client

2025-01-27T15:07:42+00:00

The existence of the ceph_mds_request_head_old structure in the MDS
client code is no longer required due to improvements in handling
different MDS request header versions. This patch removes the now
redundant ceph_mds_request_head_old structure and replaces its usage
with the flexible and extensible ceph_mds_request_head structure.

Changes include:
- Modification of find_legacy_request_head to directly cast the
  pointer to ceph_mds_request_head_legacy without going through the
  old structure.
- Update sizeof calculations in create_request_message to use
  offsetofend for consistency and future-proofing, rather than
  referencing the old structure.
- Use of the structured ceph_mds_request_head directly instead of the
  old one.

Additionally, this consolidation normalizes the handling of
request_head_version v1 to align with versions v2 and v3, leading to
a more consistent and maintainable codebase.

These changes simplify the codebase and reduce potential confusion
stemming from the existence of an obsolete structure.

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

ceph: Use no_printk() helper

2024-03-19T15:11:42+00:00

When printk-indexing is enabled, each printk() invocation emits a
pi_entry structure.  This is even true when the call is protected by an
always-false check: while the actual code to print the message is
optimized out by the compiler, the pi_entry structure is still emitted.

Fix this by replacing "if (0) printk(...)" constructs by calls to the
no_printk() helper.

This reduces the size of an arm64 kernel with CONFIG_PRINTK_INDEX=y and
CONFIG_CEPH_FS=y by ca. 4 KiB.
