xfs: detect incorrect gaps in inode btree [v24.5]
This series continues the corrections for a couple of problems I found in the inode btree scrubber. The first problem is that we don't directly check the inobt records have a direct correspondence with the finobt records, and vice versa. The second problem occurs on filesystems with sparse inode chunks -- the cross-referencing we do detects sparseness, but it doesn't actually check the consistency between the inobt hole records and the rmap data.

xfs: standardize btree record checking code [v24.5]
While I was cleaning things up for 6.1, I noticed that the btree _query_range and _query_all functions don't perform the same checking that the _get_rec functions perform. In fact, they don't perform /any/ sanity checking, which means that callers aren't warned about impossible records.
Therefore, hoist the record validation and complaint logging code into separate functions, and call them from any place where we convert an ondisk record into an incore record. For online scrub, we can replace checking code with a call to the record checking functions in libxfs, thereby reducing the size of the codebase.

xfs: convert xfs_ialloc_has_inodes_at_extent to return keyfill scan results
Convert the xfs_ialloc_has_inodes_at_extent function to return keyfill scan results because for a given range of inode numbers, we might have no indexed inodes at all; the entire region might be allocated ondisk inodes; or there might be a mix of the two.
Unfortunately, sparse inodes adds to the complexity, because each inode record can have holes, which means that we cannot use the generic btree _scan_keyfill function because we must look for holes in individual records to decide the result. On the plus side, online fsck can now detect sub-chunk discrepancies in the inobt.

Pull moar xfs updates from Darrick Wong: "This contains a fix for a deadlock in the allocator. It continues the slow march towards being able to offline AGs, and it refactors the interface to the xfs allocator to be less indirection happy.
Summary:
- Fix a deadlock in the free space allocator due to the AG-walking algorithm forgetting to follow AG-order locking rules
- Make the inode allocator prefer existing free inodes instead of failing to allocate new inode chunks when free space is low
- Set minleft correctly when setting allocator parameters for bmap changes
- Fix uninitialized variable access in the getfsmap code
- Make a distinction between active and passive per-AG structure references. For now, active references are taken to perform some work in an AG on behalf of a high level operation; passive references are used by lower level code to finish operations started by other threads. Eventually this will become part of online shrink
- Split out all the different allocator strategies into separate functions to move us away from design antipattern of filling out a huge structure for various differentish things and issuing a single function multiplexing call
- Various cleanups in the filestreams allocator code, which we might very well want to deprecate instead of continuing
- Fix a bug with the agi rotor code that was introduced earlier in this series"

xfs: per-ag centric allocation alogrithms
This series continues the work towards making shrinking a filesystem possible. We need to be able to stop operations from taking place on AGs that need to be removed by a shrink, so before shrink can be implemented we need to have the infrastructure in place to prevent incursion into AGs that are going to be, or are in the process, of being removed from active duty.
The focus of this is making operations that depend on access to AGs use the perag to access and pin the AG in active use, thereby creating a barrier we can use to delay shrink until all active uses of an AG have been drained and new uses are prevented.
This series starts by fixing some existing issues that are exposed by changes later in the series. They stand alone, so can be picked up independently of the rest of this patchset.
The most complex of these fixes is cleaning up the mess that is the AGF deadlock avoidance algorithm. This algorithm stores the first block that is allocated in a transaction in tp->t_firstblock, then uses this to try to limit future allocations within the transaction to AGs at or higher than the filesystem block stored in tp->t_firstblock. This depends on one of the initial bug fixes in the series to move the deadlock avoidance checks to xfs_alloc_vextent(), and then builds on it to relax the constraints of the avoidance algorithm to only be active when a deadlock is possible.
We also update the algorithm to record allocations from higher AGs that are allocated from, because we when we need to lock more than two AGs we still have to ensure lock order is correct. Therefore we can't lock AGs in the order 1, 3, 2, even though tp->t_firstblock indicates that we've allocated from AG 1 and so AG is valid to lock. It's not valid, because we already hold AG 3 locked, and so tp->t-first_block should actually point at AG 3, not AG 1 in this situation.
It should now be obvious that the deadlock avoidance algorithm should record AGs, not filesystem blocks. So the series then changes the transaction to store the highest AG we've allocated in rather than a filesystem block we allocated. This makes it obvious what the constraints are, and trivial to update as we lock and allocate from various AGs.
With all the bug fixes out of the way, the series then starts converting the code to use active references. Active reference counts are used by high level code that needs to prevent the AG from being taken out from under it by a shrink operation. The high level code needs to be able to handle not getting an active reference gracefully, and the shrink code will need to wait for active references to drain before continuing.
Active references are implemented just as reference counts right now - an active reference is taken at perag init during mount, and all other active references are dependent on the active reference count being greater than zero. This gives us an initial method of stopping new active references without needing other infrastructure; just drop the reference taken at filesystem mount time and when the refcount then falls to zero no new references can be taken.
In future, this will need to take into account AG control state (e.g. offline, no alloc, etc) as well as the reference count, but right now we can implement a basic barrier for shrink with just reference count manipulations. As such, patches to convert the perag state to atomic opstate fields similar to the xfs_mount and xlog opstate fields follow the initial active perag reference counting patches.
The first target for active reference conversion is the for_each_perag*() iterators. This captures a lot of high level code that should skip offline AGs, and introduces the ability to differentiate between a lookup that didn't have an online AG and the end of the AG iteration range.
From there, the inode allocation AG selection is converted to active references, and the perag is driven deeper into the inode allocation and btree code to replace the xfs_mount. Most of the inode allocation code operates on a single AG once it is selected, hence it should pass the perag as the primary referenced object around for allocation, not the xfs_mount. There is a bit of churn here, but it emphasises that inode allocation is inherently an allocation group based operation.
Next the bmap/alloc interface undergoes a major untangling, reworking xfs_bmap_btalloc() into separate allocation operations for different contexts and failure handling behaviours. This then allows us to completely remove the xfs_alloc_vextent() layer via restructuring the xfs_alloc_vextent/xfs_alloc_ag_vextent() into a set of realtively simple helper function that describe the allocation that they are doing. e.g. xfs_alloc_vextent_exact_bno().
This allows the requirements for accessing AGs to be allocation context dependent. The allocations that require operation on a single AG generally can't tolerate failure after the allocation method and AG has been decided on, and hence the caller needs to manage the active references to ensure the allocation does not race with shrink removing the selected AG for the duration of the operation that requires access to that allocation group.
Other allocations iterate AGs and so the first AG is just a hint - these do not need to pin a perag first as they can tolerate not being able to access an AG by simply skipping over it. These require new perag iteration functions that can start at arbitrary AGs and wrap around at arbitrary AGs, hence a new set for for_each_perag_wrap*() helpers to do this.
Next is the rework of the filestreams allocator. This doesn't change any functionality, but gets rid of the unnecessary multi-pass selection algorithm when the selected AG is not available. It currently does a lookup pass which might iterate all AGs to select an AG, then checks if the AG is acceptible and if not does a "new AG" pass that is essentially identical to the lookup pass. Both of these scans also do the same "longest extent in AG" check before selecting an AG as is done after the AG is selected.
IOWs, the filestreams algorithm can be greatly simplified into a single new AG selection pass if the there is no current association or the currently associated AG doesn't have enough contiguous free space for the allocation to proceed. With this simplification of the filestreams allocator, it's then trivial to convert it to use for_each_perag_wrap() for the AG scan algorithm.
