From fca8c805425c0d9435097a6c780e95332e54613a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 11 Jul 2018 22:25:59 -0700 Subject: xfs: remove xfs_reflink_trim_irec_to_next_cow We already have to check for overlapping COW extents everytime we come back to a page in xfs_writepage_map / xfs_map_cow, so this additional trim is not required.

This prepares the latter to no longer require a dfops parameter. Note that xfs_itruncate_extents_flags() associates a local dfops with a transaction provided from the caller. Since there are multiple callers, set and reset ->t_dfops before the function returns to avoid exposure of stack memory to the caller.

The only caller of that function with a non-NULL dfops is from deferred completion context, which already has attached to ->t_dfops. In addition to that, the only actual reference of a.dfops is the cursor duplication function, which means the field is effectively unused. Remove the dfops field from the bc_private.a union. Any future users can acquire the dfops from the transaction. This patch does not change behavior. Signed-off-by: Brian Foster Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.

It immediately dereferences the pointer to help determine how to initialize the bma.minleft field. The remaining accesses are related to modifying btree format forks, which is only relevant for !COW fork callers. The reflink code passes a NULL transaction to xfs_bmapi_write() in a couple places that do COW fork unwritten conversion. The purpose of the firstblock field is to track the first block allocation in the current transaction, so technically firstblock should not be required for these callers either. Tweak xfs_bmapi_write() to initialize the bma correctly without accessing the firstblock pointer if no transaction is provided in the first place. Update the reflink callers to pass NULL instead of otherwise unused firstblock references. Signed-off-by: Brian Foster Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.

The one outlier is xlog_recover_process_intents(), which simply passes a dummy value because a valid pointer is required. This firstblock variable can simply be removed. At this point we could remove the xfs_defer_init() firstblock parameter and initialize ->t_firstblock directly. Even that is not necessary, however, because ->t_firstblock is automatically reinitialized in the new transaction on a transaction roll. Since xfs_defer_init() should never occur more than once on a particular transaction (since the corresponding finish will roll it), replace the reinit from xfs_defer_init() with an assert that verifies the transaction has a NULLFSBLOCK firstblock.

Drop the hacky old dfops replacement logic and use the one associated with the transaction.

Remove all such boilerplate deferred ops code. In doing so, we change each case over to use the dfops in the transaction and specifically eliminate: - The on-stack dfops and associated xfs_defer_init() call, as the internal dfops is initialized on transaction allocation. - xfs_bmap_finish() calls that precede a final xfs_trans_commit() of a transaction. - xfs_defer_cancel() calls in error handlers that precede a transaction cancel. The only deferred ops calls that remain are those that are non-deterministic with respect to the final commit of the associated transaction or are open-coded due to special handling.

The xfs_defer_ops parameter is therefore no longer necessary and can be removed. Since most xfs_defer_finish() callers also have to consider xfs_defer_cancel() on error, update the latter to also receive the transaction for consistency. The log recovery code contains an outlier case that cancels a dfops directly without an available transaction. Retain an internal wrapper to support this outlier case for the time being.

These calls imply that the associated object is "held" by the transaction such that when rolled, the item can be immediately joined to a follow up transaction. For buffers, this means the buffer remains locked and held after each roll. For inodes, this means that the inode remains locked. Failure to join a held item to the dfops structure means the associated object pins the tail of the log while dfops processing completes, because the item never relogs and is not unlocked or released until deferred processing completes. Currently, all buffers that are held in transactions (XFS_BLI_HOLD) with deferred operations are explicitly joined to the dfops. This is not the case for inodes, however, as various contexts defer operations to transactions with held inodes without explicit joins to the associated dfops (and thus not relogging). While this is not a catastrophic problem, it is not ideal. Given that we want to eventually relog such items automatically during dfops processing, start by explicitly adding these missing xfs_defer_ijoin() calls. A call is added everywhere an inode is joined to a transaction without transferring lock ownership and said transaction runs deferred operations. All xfs_defer_ijoin() calls will eventually be replaced by automatic dfops inode relogging. This patch essentially implements the behavior change that would otherwise occur due to automatic inode dfops relogging. Signed-off-by: Brian Foster Reviewed-by: Darrick J.

This is slightly inconsistent with transaction commit error handling where a failed commit cleans up the transaction before returning. More significantly, the only requirement for exposure of ->dop_pending outside of xfs_defer_finish() is so that xfs_defer_cancel() can drain it on error. Since the only recourse of xfs_defer_finish() errors is cancellation, mirror the transaction logic and cancel remaining dfops before returning from xfs_defer_finish() with an error. Beside simplifying xfs_defer_finish() semantics, this ensures that xfs_defer_finish() always returns with an empty ->dop_pending and thus facilitates removal of the list from xfs_defer_ops.

At this point, there are no more external xfs_defer_ops users left. All instances of xfs_defer_ops are embedded in the transaction, which means we can safely pass the transaction down to the dfops add interface. Update xfs_defer_add() to receive the transaction as a parameter. Various subsystems implement wrappers to allocate and construct the context specific data structures for the associated deferred operation type. Update these to also carry the transaction down as needed and clean up unused dfops parameters along the way. This removes most of the remaining references to struct xfs_defer_ops throughout the code and facilitates removal of the structure. Signed-off-by: Brian Foster Reviewed-by: Darrick J.

The external dfops mechanism is unused and thus everywhere a (permanent) transaction is accessible the associated dfops structure is as well. Remove the xfs_defer_ops structure and fold the list_head into the transaction. Also remove the last remnant of external dfops in xfs_trans_dup(). Signed-off-by: Brian Foster Reviewed-by: Darrick J.
