• Type: Bug
• Resolution: Fixed

• Fix Version/s: Lustre 2.15.0
• Severity: 3
• Assignee: Lai Siyao
• Reporter: Lai Siyao

Description

When multiple processes call ll_update_default_lsm_md() at the same time, it should check whether lli_default_lsm_md is set, if so, free it before setting it to the one from lustre_md, otherwise it will be set to the last one, and the default_lsm set before it are leaked.
