commit 41c964fdbca552b045568967a2bb5dae0e878b7c
Author: Amitay Isaacs <[email protected]>
Date: Wed Nov 30 12:23:04 2016 +1100
ctdb-recovery: Start recovery helper with ctdb_vfork_exec
The recovery helper does it's own logging, so there is no need to
pass logfd.

ctdb-locking: Start locking helper using ctdb_vfork_exec
This avoids the extra argument of logfd to ctdb_lock_helper. The log
messages from lock helper are captured by ctdbd.

ctdb-logging: Refactor logging code
This extracts the code from following files:
- server/ctdb_logging.c
- server/ctdb_logging_file.c
- server/ctdb_logging_syslog.c
This is in preparation for each daemon (and some processes) doing
their own loging instead of relying on CTDB.
