os/bluestore: simplify allocator release flow #12343

merged 7 commits into from Dec 16, 2016

Commits on Dec 15, 2016

  1. os/bluestore: release alloc directly into usable pool 

    Wait until after the kv transaction commits, and then
release extents directly into the usable pool.

This will let us remove the commit_{start,end} business.

  4. os/bluestore/BlueFS: defer releasing extents explicitly 

    Don't rely on the Allocator to do this for us (that is
about to go away!).

  7. os/bluestore: clone_range of len 0 creates but does not size object 

    This mimics, roughly,

 open(..., O_WRONLY|O_CREAT, ...)
 seek(...)
 if (len > 0)
   write(...)
