[Samba] SAMBA: Share specific log files

[Srini]

Hi all,

We find that the log messages gets correctly redirected after a
certain period of time from a samba service restart (3 or 4 minutes).
Till this initial period of time, it looks like the log messages are
getting redirected to the default log file but after this time and
with the below code change, it is getting redirected into the
appropriate share specific log file. Does anyone have any ideas on why
this is not happening from beginning??

Thanks

Srini
