    mm: vmscan: refactor updating current->reclaim_state · c7b23b68
    Yosry Ahmed authored
    During reclaim, we keep track of pages reclaimed from other means than
    LRU-based reclaim through scan_control->reclaim_state->reclaimed_slab,
    which we stash a pointer to in current task_struct.
    
    However, we keep track of more than just reclaimed slab pages through
    this.  We also use it for clean file pages dropped through pruned inodes,
    and xfs buffer pages freed.  Rename reclaimed_slab to reclaimed, and add a
    helper function that wraps updating it through current, so that future
    changes to this logic are contained within include/linux/swap.h.
