| Description |
|
In the current Lustre, an OPEN ibits lock returned to a client is mandatorily setting to specific lock mode:
For DoM files, it would better to return the corresponding DOM ibits lock together (combined) with OPEN ibits to a client during the open() or open-ahead(https://jira.whamcloud.com/browse/LU-16429) for the possible subsequent read or write, which can reduce extra lock traffic for DOM ibits lock. The client needs to handle for PW or PW OPEN ibits lock properly. |
