xfs: store an agbno in struct xfs_imap

2026-06-09T07:14:42+00:00

The xfs_imap structure is embedded into the xfs_inode, which means the
size of it directly affects the inode size.  Replacing the xfs_daddr_t
with an xfs_agbno_t and taking the AG information from other easily
available sources allows us to shrink the structure including the
typical padding from 16 bytes to 8 bytes.

As a side-effect the debugging check in xfs_imap() naturally now
converges to a stricter variant that checks that the cluster is located
inside a single AG, and not just inside the entire device.

xfs: massage xfs_imap_to_bp into xfs_read_icluster

2026-06-09T07:14:42+00:00

xfs_imap_to_bp only uses the im_blkno field from struct xfs_imap, so pass
that directly.  Rename the function to xfs_read_icluster, which describes
the functionality much better and matches other helpers like xfs_read_agf
and xfs_read_agi.

xfs: remove im_len field in struct xfs_imap

2026-06-09T07:14:42+00:00

im_len is always set to the same value for a given file system,
which makes it redundant.

xfs: remove the i_ino field in struct xfs_inode

2026-06-09T07:14:41+00:00

Now that the VFS inode has a u64 i_ino field, there is no need to store
a copy of the inode number in the xfs_inode structure.

Introduce an I_INO() wrapper as a shortcut to the inode number so that
we don't have to propagate the VFS inode everywhere.

The only non-obvious part is the clearing of i_ino to 0 for RCU freeing
the inode.  None of this calls into VFS paths, which makes clearing the
VFS inode field here just as safe as clearing the old field in the
xfs_inode.

xfs: convert xchk_inode_xref_set_corrupt to xchk_ip_xref_set_corrupt

2026-06-09T07:14:41+00:00

All xref corruption reports have the xfs_inode structure, so switch
the helper to work based on that.
