[PATCH 5.4 06/25] xfs: merge the ->diff_items defer op into ->create_intent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christoph Hellwig <hch@xxxxxx>

commit d367a868e46b025a8ced8e00ef2b3a3c2f3bf732 upstream.

This avoids a per-item indirect call, and also simplifies the interface
a bit.
