* xfs: use a struct timespec64 for the in-core crtimeChristoph Hellwig2019-11-137-18/+14
| | | | | | | | | | | struct xfs_icdinode is purely an in-memory data structure, so don't use a log on-disk structure for it. This simplifies the code a bit, and also reduces our include hell slightly. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.

| | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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.

* xfs: actually check xfs_btree_check_block return in xfs_btree_islastblockDarrick J. Wong2019-11-112-27/+17
| | | | | | | | | | | | | | | 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: Darrick J.

| | | | | | | | | Move the node header size field to struct xfs_da_geometry, and remove the now unused non-directory dir ops infrastructure. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>
* xfs: add a btree entries pointer to struct xfs_da3_icnode_hdrChristoph Hellwig2019-11-118-86/+60
| | | | | | | | | | | | | All but two callers of the ->node_tree_p dir operation already have a xfs_da3_icnode_hdr from a previous call to xfs_da3_node_hdr_from_disk at hand. Add a pointer to the btree entries to struct xfs_da3_icnode_hdr to clean up this pattern. The two remaining callers now expand the whole header as well, but that isn't very expensive and not in a super hot path anyway. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
