...ble on the server, and I suspect I may need that for efficiency's sake (a lot of files are being locked/unlocked). I downloaded samba-latest.tar.gz and noticed that source/smbd/blocking.c seems to respond to these by setting LOCK_MAND versions of flock states, which are available only for "sys_flock" and rumored not to affect normal Linux programming. Can file locks block a Samba open request? Can they be set by, or made to affect, Linux programming on the server (I don't care about NFS file opens, only local opens on the server)? Does this drive special Samba kernel code, or does sm...
