    ext4: generalize extents status tree search functions · ad431025
    Eric Whitney authored
    Ext4 contains a few functions that are used to search for delayed
    extents or blocks in the extents status tree.  Rather than duplicate
    code to add new functions to search for extents with different status
    values, such as written or a combination of delayed and unwritten,
    generalize the existing code to search for caller-specified extents
    status values.  Also, move this code into extents_status.c where it
    is better associated with the data structures it operates upon, and
    where it can be more readily used to implement new extents status tree
    functions that might want a broader scope for i_es_lock.
    
    Three missing static specifiers in RFC version of patch reported and
    fixed by Fengguang Wu <fengguang.wu@intel.com>.
