s3:dbwrap_watch: call dbwrap_watched_trigger_wakeup() outside of the low level record lock

2022-07-26T14:32:35+00:00

This gives a nice speed up, as it's unlikely for the waiters to hit
contention.

The following test with 256 commections all looping with open/close
on the same inode (share root) is improved drastically:

  smbtorture //127.0.0.1/m -Uroot%test smb2.create.bench-path-contention-shared \
     --option='torture:bench_path=' \
     --option="torture:timelimit=60" \
     --option="torture:nprocs=256"

From some like this:

   open[num/s=8800,avslat=0.021445,minlat=0.000095,maxlat=0.179786]
   close[num/s=8800,avslat=0.021658,minlat=0.000044,maxlat=0.179819]
