Description

Sanger has hit an LBUG on its clients:
ASSERTION(atomic_read(&import->imp_refcount) < 0x5a5a5a) failed

This appears to be a dupe of LU-919, but that patch was never landed on b1_8, though the patch was created. Is there any chance to get it landed? It failed the maloo test, but it doesn't look like that failure was investigated:

• duplicates: LU-919 Multiple wrong LBUGs checking cfs_atomic_t vars/fields with inacurate poison value of 0x5a5a5a
• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
