2019-11-22xfs: remove the mappedbno argument to xfs_da_read_bufChristoph Hellwig1-2/+2
Move the code for reading an already mapped block into xfs_da3_node_read_mapped, which is the only caller ever passing a block number in the mappedbno argument and replace the mappedbno argument with the simple xfs_dabuf_get flags.

2019-11-10xfs: add a bests pointer to struct xfs_dir3_icfree_hdrChristoph Hellwig1-0/+6

2019-11-10xfs: add an entries pointer to struct xfs_dir3_icleaf_hdrChristoph Hellwig1-1/+8
All callers of the ->node_tree_p dir operation already have a struct xfs_dir3_icleaf_hdr from a previous call to xfs_da_leaf_hdr_from_disk at hand, or just need slight changes to the calling conventions to do so. Add a pointer to the entries to struct xfs_dir3_icleaf_hdr to clean up this pattern. To make this possible the xfs_dir3_leaf_log_ents function grow a new argument to pass the xfs_dir3_icleaf_hdr that call callers already have, and xfs_dir2_leaf_lookup_int returns the xfs_dir3_icleaf_hdr to the callers so that they can later use it.

2017-04-03xfs: rework the inline directory verifiersDarrick J. Wong1-2/+1
The inline directory verifiers should be called on the inode fork data, which means after iformat_local on the read side, and prior to ifork_flush on the write side. This makes the fork verifier more consistent with the way buffer verifiers work -- i.e. they will operate on the memory buffer that the code will be reading and writing directly. Furthermore, revise the verifier function to return -EFSCORRUPTED so that we don't flood the logs with corruption messages and assert notices. This has been a particular problem with xfs/348, which triggers the XFS_WANT_CORRUPTED_RETURN assertions, which halts the kernel when CONFIG_XFS_DEBUG=y. Disk corruption isn't supposed to do that, at least not in a verifier. Reviewed-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Darrick J.
