From d2845519b0723c5d5a0266cbf410495f9b8fd65c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig hch@lst.de Date: Wed, 23 Jul 2025 14:19:44 +0200 Subject: [PATCH] xfs: fully decouple XFS_IBULK* flags from XFS_IWALK* flags
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.

[ Upstream commit 83a80e95e797a2a6d14bf7983e5e6eecf8f5facb ]
xfs_trans_alloc_empty only shares the very basic transaction structure allocation and initialization with xfs_trans_alloc.
Split out a new __xfs_trans_alloc helper for that and otherwise decouple xfs_trans_alloc_empty from xfs_trans_alloc.

xfs_trans_alloc_empty can't return errors, so return the allocated transaction directly instead of an output double pointer argument.

[ Upstream commit d2845519b0723c5d5a0266cbf410495f9b8fd65c ]
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.
