Brian Foster 12818d24db xfs: rework log recovery to submit buffers on LSN boundaries ... The fix to log recovery to update the metadata LSN in recovered buffers introduces the requirement that a buffer is submitted only once per current LSN. Log recovery currently submits buffers on transaction boundaries. This is not sufficient as the abstraction between log records and transactions allows for various scenarios where multiple transactions can share the same current LSN. If independent transactions share an LSN and both modify the same buffer, log recovery can incorrectly skip updates and leave the filesystem in an inconsisent state. In preparation for proper metadata LSN updates during log recovery, update log recovery to submit buffers for write on LSN change boundaries rather than transaction boundaries. Explicitly track the current LSN in a new struct xlog field to handle the various corner cases of when the current LSN may or may not change.
