xfs: remove the expr argument to XFS_TEST_ERROR

2025-09-18T15:32:02Z

Don't pass expr to XFS_TEST_ERROR. Most calls pass a constant false, and the places that do pass an expression become cleaner by moving it out. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Carlos Maiolino

xfs: return the allocated transaction from xfs_trans_alloc_empty

2025-07-24T15:30:13Z

xfs_trans_alloc_empty can't return errors, so return the allocated transaction directly instead of an output double pointer argument. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Carlos Maiolino

xfs: recover CoW leftovers in the realtime volume

2024-12-23T21:06:13Z

xfs: wire up realtime refcount btree cursors

2024-12-23T21:06:12Z

Wire up realtime refcount btree cursors wherever they're needed throughout the code base. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: add a realtime flag to the refcount update log redo items

2024-12-23T21:06:11Z

Extend the refcount update (CUI) log items with a new realtime flag that indicates that the updates apply against the realtime refcountbt. We'll wire up the actual refcount code later. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: prepare refcount functions to deal with rtrefcountbt

2024-12-23T21:06:10Z

Prepare the high-level refcount functions to deal with the new realtime refcountbt and its slightly different conventions. Provide the ability to talk to either refcountbt or rtrefcountbt formats from the same high level code. Note that we leave the _recover_cow_leftovers functions for a separate patch so that we can convert it all at once. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: namespace the maximum length/refcount symbols

2024-12-23T21:06:10Z

Actually namespace these variables properly, so that readers can tell that this is an XFS symbol, and that it's for the refcount functionality. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: add a realtime flag to the rmap update log redo items

2024-12-23T21:06:04Z

Extend the rmap update (RUI) log items to handle realtime volumes by adding a new log intent item type. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: simplify the xfs_rmap_{alloc,free}_extent calling conventions

2024-12-23T21:06:03Z

Simplify the calling conventions by allowing callers to pass a fsbno (xfs_fsblock_t) directly into these functions, since we're just going to set it in a struct anyway. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: store a generic group structure in the intents

2024-11-05T21:38:30Z

Replace the pag pointers in the extent free, bmap, rmap and refcount intent structures with a pointer to the generic group to prepare for adding intents for realtime groups. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J. Wong
