[PATCH v3 00/10] xfs_ioc_bulkstat code refactoring and consolidation

[Jeff Liu]

Hi folk,

This is the revised patches for xfs_ioc_bulkstat consolidation and code
refactoring. As per Christoph's comments, I'm not include the per AG
inumber patch in this series given that I don't actually introduce the
relevant inumbers interface now. Similar to that reason, I also dropped
the per AG bulkstat patch, it would be included in parallel quota check
series.


v3->v2:
- one major bug fix is at xfs_bulkstat_ag_ichunk() regarding the user buffer
  pointer operations, it should be defined as a pointer-to-pointer since it
  would be updated inside xfs_bulkstat_ag_ichunk().

- separate xfs_inumber consolidate patch into two patches, the first one
  fix the formater function return value and consolidate the codes, another
  one does the actual logic changes for better error handling.

- Add a separate patch to get rid of the redundant user buffer count
  checks at xfs_bulkstat()

- fixed agino calculation issue at xfs_bulkstat_grab_ichunk().

Any comments are welcome!
