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
- 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!
