[LU-12607] Use zfs internals to manage the zrlock - Whamcloud Community JIRA

Details

Type: Bug
Resolution: Unresolved
Priority: Major
Fix Version/s: None
Affects Version/s: Lustre 2.12.2
Labels:
- ORNL
Environment:
lustre servers using ZFS 0.8.1+

Severity:
3
Rank (Obsolete):

Description

The fix for ~~LU-12510~~ was only a temporary work around. Currently Lustre manages the zrlock directly but this can collide with ZFS doing with the same thing which can lead to dead locks. The proper fix it so use the ZFS lock management functions provided by ZFS. https://github.com/zfsonlinux/zfs/pull/9027 landed a patch to export the needed functions for Lustre to use. This ticket will track the proper locking implementation.
