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. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>

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.

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. Signed-off-by: Darrick J.
