[LU-9385] mdt_add_dirty_flag() should not use MDS_INODELOCK_XATTR

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.10.0
• Severity: 3
• Assignee: John Hammond

Description

Clients use the {{MDS_HSM_STATE_

{GET,SET}

}} RPCs to get and set the HSM state of a file and not the HSM xattr. Thus the MDT should not use MDS_INODELOCK_XATTR to protect updates to the HSM state. A local (preferably already existing) mutex or semaphore in the MDT object should be used instead.
