--- Doc Text *updated* ---
Previously, the eager locking option was used to provide good performance for file access, however, directory access suffered when eager-lockk was enabled for some use cases. To overcome this problem, A a new option 'other-eager-lock' is introduced. This option keeps eager-locking enabled for regular files but disabled for directory accesses.

As a result, Use cases where directories are accessed from multiple clients can benefit from disabling eager-locking for directories without losing performance on file accesses.
