Jeremy Allison 9e88a7ebe9 After conversations with Andrew, improved the robustness of the ... sharemode db in the following way. Originally, on startup and shutdown, smbd would scan the share mode db to ensure it was correct. This lead to scalability issues as scans lock the db for quite a long time. Andrew had the brainstorm that we only care about the record we're about to read. This new code (small change really, but quite significant) causes get_share_modes() to do a process_exists() call against each pid in each record, and to delete any that don't and re-write the entry if any dead records were detected. This allowed me to remove the startup/shutdown scans of the db (they can be added into smbstatus if anyone really cares to have them back). This will please the vfs author who was worried about the time taken on open() calls, and will lead to much greater robustness and scalability in the share mode db. We need much testing of this, and also netbench tests to ensure the extra process_exists() calls don't hurt performance (they shouldn't it's a very simple system call). Jeremy.
