Clean up xfs_reclaim_inodes() callers. Most callers want blocking behaviour, so just make the existing SYNC_WAIT behaviour the default. For the xfs_reclaim_worker(), just call xfs_reclaim_inodes_ag() directly because we just want optimistic clean inode reclaim to be done in the background. For xfs_quiesce_attr() we can just remove the inode reclaim calls as they are a historic relic that was required to flush dirty inodes that contained unlogged changes. We now log all changes to the inodes, so the sync AIL push from xfs_log_quiesce() called by xfs_quiesce_attr() will do all the required inode writeback for freeze. Seeing as we now want to loop until all reclaimable inodes have been reclaimed, make xfs_reclaim_inodes() loop on the XFS_ICI_RECLAIM_TAG tag rather than having xfs_reclaim_inodes_ag() tell it that inodes were skipped. This is much more reliable and will always loop until all reclaimable inodes are reclaimed. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
