Description
C_AioRead::finish places bits of a striped AioRead into the StripedReadResult
object's partial field for later assembly; however it does so without holding a lock
so the updates race and can damage the state. The damage is noticed in assemble_result(),
but happened earlier in add_partial_sparse_result.
The fix is to modify partial only while holding the AioCompletion lock while modifying
destriper->partial.
