See http://www.infradead.org/rpr.html Currently only the new agcount is passed to xfs_initialize_perag, which requires lookups of existing AGs to skip them and complicates error handling. Also pass the previous agcount so that the range that xfs_initialize_perag operates on is exactly defined. That way the extra lookups can be avoided, and error handling can clean up the exact range from the old count to the last added perag structure.

See http://www.infradead.org/rpr.html There is no good reason to have two different routines for freeing perag structures for the unmount and error cases. Add two arguments to specify the range of AGs to free to xfs_free_perag, and use that to replace xfs_free_unused_perag_range. The addition RCU grace period for the error case is harmless, and the extra check for the AG to actually exist is not required now that the callers pass the exact known allocated range.

See http://www.infradead.org/rpr.html Primary superblock buffers that change the file system geometry after a growfs operation can affect the operation of later CIL checkpoints that make use of the newly added space and allocation groups. Apply the changes to the in-memory structures as part of recovery pass 2, to ensure recovery works fine for such cases. In the future we should apply the logic to other updates such as features bits as well.

See http://www.infradead.org/rpr.html Updates to the file system geometry in growfs need to be committed to stable store before the allocator can see them to avoid that they are in the same CIL checkpoint as transactions that make use of this new information, which will make recovery impossible or broken. To do this add two new helpers to prepare a superblock for direct manipulation of the on-disk buffer, and to commit these updates while holding the buffer locked (similar to what xfs_sync_sb_buf does) and use those in growfs instead of applying the changes through the deltas in the xfs_trans structure (which also happens to shrink the xfs_trans structure a fair bit). The rtbmimap repair code was also using the transaction deltas and is converted to also update the superblock buffer directly under the buffer lock. This new method establishes a locking protocol where even in-core superblock fields must only be updated with the superblock buffer locked. For now it is only applied to affected geometry fields, but in the future it would make sense to apply it universally.

See http://www.infradead.org/rpr.html Split xfs_trans_mod_sb into separate helpers for the different counts. While the icount and ifree counters get their own helpers, the handling for fdblocks and frextents merges the delalloc and non-delalloc cases to keep the related code together.
