Chandan Babu R 5b35d922c5 xfs: Decouple XFS_IBULK flags from XFS_IWALK flags
A future commit will add a new XFS_IBULK flag which will not have a
corresponding XFS_IWALK flag. In preparation for the change, this commit
separates XFS_IBULK_* flags from XFS_IWALK_* flags.

Darrick J. Wong 39ee2239a5 xfs: remove all *_ITER_CONTINUE values
Iterator functions already use 0 to signal "continue iterating", so get
rid of the #defines and just do it directly.

Darrick J. Wong e7ee96dfb8 xfs: remove all *_ITER_ABORT values
Use -ECANCELED to signal "stop iterating" instead of these magical
*_ITER_ABORT values, since it's duplicative.

Darrick J. Wong 13d59a2a61 xfs: specify AG in bulk req
Add a new xfs_bulk_ireq flag to constrain the iteration to a single AG.
If the passed-in startino value is zero then we start with the first
inode in the AG that the user passes in; otherwise, we iterate only
within the same AG as the passed-in inode.

Darrick J. Wong 3e5a428b26 xfs: poll waiting for quotacheck
Create a pwork destroy function that uses polling instead of
uninterruptible sleep to wait for work items to finish so that we can
touch the softlockup watchdog.  IOWs, gross hack.

Darrick J. Wong 04b8fba2e1 xfs: refactor iwalk code to handle walking inobt records
Refactor xfs_iwalk_ag_start and xfs_iwalk_ag so that the bits that are
particular to bulkstat (trimming the start irec, starting inode
readahead, and skipping empty groups) can be controlled via flags in the
iwag structure.

This enables us to add a new function to walk all inobt records which
will be used for the new INUMBERS implementation in the next patch.

Darrick J. Wong a211432c27 xfs: create simplified inode walk function
Create a new iterator function to simplify walking inodes in an XFS
filesystem.  This new iterator will replace the existing open-coded
walking that goes on in various places.
