xfs: use xfs_csn_t for xlog_cil_push_now() push_seq parameter

2026-07-08T12:54:05Z

The push_seq argument to xlog_cil_push_now() carries a CIL checkpoint sequence number, not a log sequence number (LSN). Change the parameter type from xfs_lsn_t to xfs_csn_t to correctly reflect its semantics and match the surrounding types. Both types are int64_t under the hood, so this is a type-annotation fix with no behavioural change. Signed-off-by: Jinliang Zheng Reviewed-by: "Darrick J. Wong" Signed-off-by: Carlos Maiolino

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

xfs: directly include xfs_platform.h

2026-01-21T11:57:16Z

The xfs.h header conflicts with the public xfs.h in xfsprogs, leading to a spurious difference in all shared libxfs files that have to include libxfs_priv.h in userspace. Directly include xfs_platform.h so that we can add a header of the same name to xfsprogs and remove this major annoyance for the shared code. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J.

xfs: improve the ->iop_format interface

2026-01-21T11:57:16Z

Export a higher level interface to format log items. The xlog_format_buf structure is hidden inside xfs_log_cil.c and only accessed using two helpers (and a wrapper build on top), hiding details of log iovecs from the log items. This also allows simply using an index into lv_iovecp instead of keeping a cursor vec. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Carlos Maiolino

xfs: add a xlog_write_one_vec helper

2026-01-21T11:57:16Z

Add a wrapper for xlog_write for the two callers who need to build a log_vec and add it to a single-entry chain instead of duplicating the code. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Carlos Maiolino

xfs: don't use xlog_in_core_2_t in struct xlog_in_core

2025-11-12T10:09:25Z

Most accessed to the on-disk log record header are for the original xlog_rec_header. Make that the main structure, and case for the single remaining place using other union legs. This prepares for removing xlog_in_core_2_t entirely. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Reviewed-by: Carlos Maiolino Signed-off-by: Carlos Maiolino

xfs: use better names for size members in xfs_log_vec

2025-07-24T15:30:15Z

The lv_size member counts the size of the entire allocation, rename it to lv_alloc_size to make that clear. The lv_buf_len member tracks how much of lv_buf has been used up to format the log item, rename it to lv_buf_used to make that more clear.

xfs: cleanup the ordered item logic in xlog_cil_insert_format_items

xfs: don't pass the old lv to xfs_cil_prepare_item

2025-07-24T15:30:14Z

By the time xfs_cil_prepare_item is called, the old lv is still pointed to by the log item. Take it from there instead of spreading the old lv logic over xlog_cil_insert_format_items and xfs_cil_prepare_item.

xfs: add tracepoints for stale pinned inode state debug

I needed more insight into how stale inodes were getting stuck on the AIL after a forced shutdown when running fsstress. These are the tracepoints I added for that purpose. Signed-off-by: Dave Chinner Reviewed-by: Carlos Maiolino Signed-off-by: Carlos Maiolino
