2022-04-13xfs: Decouple XFS_IBULK flags from XFS_IWALK flagsChandan Babu R
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.

2019-08-30xfs: remove all *_ITER_CONTINUE valuesDarrick J. Wong
Iterator functions already use 0 to signal "continue iterating", so get rid of the #defines and just do it directly. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
2019-08-29xfs: remove all *_ITER_ABORT valuesDarrick J. Wong
Use -ECANCELED to signal "stop iterating" instead of these magical *_ITER_ABORT values, since it's duplicative. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
2019-07-04xfs: specify AG in bulk reqDarrick J. Wong
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.

2019-07-03xfs: poll waiting for quotacheckDarrick J. Wong
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. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>

Create a parallel iwalk implementation and switch quotacheck to use it. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
2019-07-02xfs: refactor iwalk code to handle walking inobt recordsDarrick J. Wong
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.

2019-07-02xfs: create simplified inode walk functionDarrick J. Wong
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>
