Add a new macro, XFS_IS_CORRUPT, which we will use to integrate some corruption reporting when the corruption test expression is true. This will be used in the next patch to remove the ugly XFS_WANT_CORRUPT* macros. Signed-off-by:

Make sure we attach dquots to both inodes before swapping their extents. This was found via manual code inspection by looking for places where we could call xfs_trans_mod_dquot without dquots attached to inodes, and confirmed by instrumenting the kernel and running xfs/328. Signed-off-by:

In xfs_iomap_write_unwritten, we need to ensure that dquots are attached to the inode and quota blocks reserved so that we capture in the quota counters any blocks allocated to handle a bmbt split. This can happen on the first unwritten extent conversion to a preallocated sparse file on a fresh mount. This was found by running generic/311 with quotas enabled. The bug seems to have been introduced in "[XFS] rework iocore infrastructure, remove some code and make it more" from ~2002? Signed-off-by:

Coverity points out that xfs_btree_islastblock doesn't check the return value of xfs_btree_check_block. Since the question "Does the cursor point to the last block in this level?" only makes sense if the caller previously performed a lookup or seek operation, the block should already have been checked. Therefore, check the return value in an ASSERT and turn the whole thing into a static inline predicate. Coverity-id: 114069 Signed-off-by:

There is no real need for xfs_dir2_data_freescan wrapper, so rename xfs_dir2_data_freescan_int to xfs_dir2_data_freescan and let the callers dereference the mount pointer from the inode. Signed-off-by:

Replace the two users of the ->data_unused_p dir ops method with a direct calculation using ->data_entry_offset, and clean them up a bit. xfs_dir2_sf_to_block already had an offset variable containing the value of ->data_entry_offset, which we are now reusing to make it clear that the initial freespace entry is at the same place that we later fill in the 1 entry, and in xfs_dir3_data_init the function is cleaned up a bit to keep the initialization of fields of a given structure close to each other, and to avoid a local variable.

The only user of the ->data_dot_entry_p and ->data_dotdot_entry_p methods is the xfs_dir2_sf_to_block function that builds block format directorys from a short form directory. It already uses pointer arithmetics with a offset variable to do so for the real entries in the directory, so switch the generation of the . and .. entries to the same scheme, and clean up some of the later pointer arithmetics to use bp->b_addr directly as well and avoid some casts.

The data_dotdot_offset value is always equal to data_entry_offset plus the fixed size of the "." entry. Right now calculating that fixed size requires an indirect call, but by the end of this series it will be an inline function that can be constant folded. Signed-off-by:

All but two callers of the ->free_bests_p dir operation already have a struct xfs_dir3_icfree_hdr from a previous call to xfs_dir2_free_hdr_from_disk at hand. Add a pointer to the bests to struct xfs_dir3_icfree_hdr to clean up this pattern. To optimize this pattern, pass the struct xfs_dir3_icfree_hdr to xfs_dir2_free_log_bests instead of recalculating the pointer there. Signed-off-by:
