------------------------------------------
Summary: NFFS - Block collation during garbage collection can
break parent file
Key: MYNEWT-165
URL: https://issues.apache.org/jira/browse/MYNEWT-165
Project: Mynewt
Issue Type: Bug
Components: NFFS
Reporter: Christopher Collins
Assignee: Christopher Collins
Fix For: v0_8_0_beta2
During garbage collection, consecutive data blocks in the area being GCed are
collated into a single block. The resulting block should inherit its ID from
its last constituent data block, as this is the ID that the parent inode and
subsequent data block reference.
The code gets this backwards; the resulting block inherits its ID from its
*first* constituent data block.
The fix is to inherit from the last block.
