xfs: remove XFS_IBULK_SAME_AG

2025-08-11T12:03:31Z

Add a new field to struct xfs_ibulk to directly pass XFS_IWALK* flags, and thus remove the need to indirect the SAME_AG flag through XFS_IBULK*. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Carlos Maiolino

xfs: fully decouple XFS_IBULK* flags from XFS_IWALK* flags

2025-08-11T12:03:19Z

Fix up xfs_inumbers to now pass in the XFS_IBULK* flags into the flags argument to xfs_inobt_walk, which expects the XFS_IWALK* flags. Currently passing the wrong flags works for non-debug builds because the only XFS_IWALK* flag has the same encoding as the corresponding XFS_IBULK* flag, but in debug builds it can trigger an assert that no incorrect flag is passed. Instead just extra the relevant flag.

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: allow bulkstat to return metadata directories

2024-11-05T21:38:32Z

Allow the V5 bulkstat ioctl to return information about metadata directory files so that xfs_scrub can find and scrub them, since they are otherwise ordinary directories. (Metadata files of course require per-file scrub code and hence do not need exposure.) Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: rename metadata inode predicates

2024-11-05T21:38:30Z

The predicate xfs_internal_inum tells us if an inumber refers to one of the inodes rooted in the superblock. Soon we're going to have internal inodes in a metadata directory tree, so this helper should be renamed to capture its limited scope. Ondisk inodes will soon have a flag to indicate that they're metadata inodes. Head off some confusion by renaming the xfs_is_metadata_inode predicate to xfs_is_internal_inode.

xfs: hide private inodes from bulkstat and handle functions

2024-04-15T21:58:48Z

We're about to start adding functionality that uses internal inodes that are private to XFS. What this means is that userspace should never be able to access any information about these files, and should not be able to open these files by handle. To prevent users from ever finding the file or mis-interactions with the security apparatus, set S_PRIVATE on the inode. Don't allow bulkstat, open-by-handle, or linking of S_PRIVATE files into the directory tree. This should keep private inodes actually private. Signed-off-by: Darrick J.

xfs: convert remaining kmem_free() to kfree()

2024-02-13T12:37:34Z

The remaining callers of kmem_free() are freeing heap memory, so we can convert them directly to kfree() and get rid of kmem_free() altogether. This conversion was done with: $ for f in `git grep -l kmem_free fs/xfs`; do > sed -i s/kmem_free/kfree/ $f > done $ Signed-off-by: Dave Chinner Reviewed-by: "Darrick J.

xfs: convert kmem_zalloc() to kzalloc()

2024-02-13T12:37:33Z

There's no reason to keep the kmem_zalloc() around anymore, it's just a thin wrapper around kmalloc(), so lets get rid of it. Signed-off-by: Dave Chinner Reviewed-by: "Darrick J. Wong" Signed-off-by: Chandan Babu R

xfs: fix reloading entire unlinked bucket lists

2023-09-25T01:12:13Z

During review of the patcheset that provided reloading of the incore iunlink list, Dave made a few suggestions, and I updated the copy in my dev tree. Unfortunately, I then got distracted by ... who even knows what ... and forgot to backport those changes from my dev tree to my release candidate branch. I then sent multiple pull requests with stale patches, and that's what was merged into -rc3. So. This patch re-adds the use of an unlocked iunlink list check to determine if we want to allocate the resources to recreate the incore list. Since lost iunlinked inodes are supposed to be rare, this change helps us avoid paying the transaction and AGF locking costs every time we open any inode. This also re-adds the shutdowns on failure, and re-applies the restructuring of the inner loop in xfs_inode_reload_unlinked_bucket, and re-adds a requested comment about the quotachecking code. Retain the original RVB tag from Dave since there's no code change from the last submission.
